One of the joys of playing Just Dance 3 is collecting all the medals. Here's the list of medals, and some tips on how to get them!

Constellation Maker
get 1 star on every song (this is where I am)
get 3 stars on every song
get 5 stars on every song
NOTE: Fairly straightforward. You have to work hard to master each song's moves. You can see the current star count by going out to the "one by one" song screen that moves through them like a jukebox. I wish they showed the star count on the all-on-one-page screen, since that's the one I use the most. They only show which songs have 5 stars on here. At this point I have 3 stars on everything and am working towards the 5 star point song by song.

Sweat and Score
reach 300 sweat points with a 3 star rating on any song
reach 400 sweat points with a 4 star rating on any song
reach 500 sweat points with a 5 star rating on any song
NOTE: Again, fairly straightforward. I find the easiest one to get 500 sweat points on is Jamaican Dance, and once you figure out the moves on that song, it's repetitive and easy.

Just Dancer
play 10 songs
play 75 songs
play 150 songs
NOTE: This is an easy one, it's simply a cumulative counter. So after a while it will naturally happen.

The Good Dancer
become a star drummer in "she's got me dancing" (score "GOOD" or better)
NOTE: this part is easy, there's two chances and it's right up front.

become a crystal miner in "pump it" (score "GOOD" or better)
NOTE: It took me FOREVER to get this to trigger. In my case I got the entry "mining part" (where crystals come from the floor) perfect, an OK in the two middle sections, and a perfect at the end mining part. It gave me the medal. So it might just be the first or last that you need. I had gotten a single perfect middle area before and it didn't trigger so it could also be that you need 2 out of the 4 of them perfect.

become a real pianist in "take on me" (score "GOOD" or better)
NOTE: Compared with the pain and agony of the crystal miner, this was a one-shot easy one. Just do well in the hands-angled-down two parts.


The Good Duet
fall in love in "Something Stupid" (score "GOOD" or better with both dancers)
NOTE: The part where she bends down to hold his hand, just move smoothly and you should get it.

go through the x-ray in "Da Funk" (score "GOOD" or better with both dancers)
NOTE: The part where you can see their bones, again not too tricky

know your moves on the ground in "Beautiful Liar" (score "GOOD" or better with both dancers)
NOTE: The part when they're both kneeling. This just takes practice.

The Good Crew
show your love in "boogie wonderland" (score "GOOD" or better with 4 dancers)
NOTE: I'm afraid I don't have four dancers, so I can't test these. Does anyone know what the rest are?

Master Simon
don't lose a single point on "STOP" moves during Simon Says mode
NOTE: The key here is to not worry about other points, because you'll always end up in a sweeping move when they tell you to stop :) Just move as little as possible so when the stop comes up you can.

Get at least 1000 points on every "SHAKE" move on Simon Says mode
NOTE: You have to shake like crazy to get it to fill up, but it is possible.

score every "CLAP" move on simon says mode
NOTE: Takes good timing, but again, possible. Luckily the clap thing gives you some warning, so it only took me a few tries to get it.


Eyes Wide Shut
get 5 stars on any song after disabling pictograms in the options menu
get 5 stars on any 3 songs after disabling pictograms in the options menu
get 5 stars on any 5 songs after disabling pictograms in the options menu
NOTE: This one is fairly easy once you get into the game. I now play with pictograms turned off all the time and it doesn't bother me at all.


Highway to Stars
get 5 stars for 2 songs in a row
get 5 stars for 4 songs in a row
get 5 stars for 6 songs in a row
NOTE: They have to be DIFFERENT SONGS so this is a matter of building your skills up in a number of songs and then doing them all in a row.


Sweat Me a River
earn 1,000 sweat points
earn 10,000 sweat points
earn 30,000 sweat points
NOTE: This is cumulative. You might as well just play in sweat mode all the time since you can get to all the songs and games anyway, and you have the added bonus of the sweat points being added up for you. You earn this fairly quickly if you do.


Marathon
play at least 5 songs in a row on non-stop shuffle
play at least 15 songs in a row on non-stop shuffle
play at least 30 songs in a row on non-stop shuffle
NOTE: I've only hit the 5 song mark because there are a number of songs in the mix that I'm just not that fond of. I'd rather choose songs I love to play. I wish you could make your own personalized playlist - in that case I'd definitely do this!


Perfectionist
finish any song with no x
finish any song with 90% of good or perfect moves
finish any song with 100% of good or perfect moves
NOTE: I'm at the 90% mark but can't get 100% yet. I'm very close on Jamaican Dance but there's always that stray "ok" that sneaks in there on the hand-swirling part :)


Ace Pair
finish any duet with 2 players getting 3 stars on both choreographies
finish any duet with 2 players getting 4 stars on both choreographies
finish any duet with 2 players getting 5 stars on both choreographies
NOTE: I'm only at 4 stars with this. I just can't get the 5 stars on Something Stupid with the mermaid which is my chosen song to try the duet with. I do fine with the diver!


Big Band Theory
finish any dance crew with all 4 players getting 3 stars
finish any dance crew with all 4 players getting 4 stars
finish any dance crew with all 4 players getting 5 stars
NOTE: I don't have four players, so I can't do this one.


Sweaty Hands
get 4 scores of 3 stars on a hold my hand choreography
get 4 scores of 4 stars on a hold my hand choreography
get 4 scores of 5 stars on a hold my hand choreography
NOTE: You have to have a dedicated partner to work on this one :) This is a SPECIFIC SONG in the specials area that you have to do, and all four "players" have to each get 3 stars to achieve the medal. If you only have two people, each person can hold one controller in their left hand and one in their right to give it a shot.

I admit I was so bad at this one that I enlisted my boyfriend and he had to go above and beyond the call of duty to achieve it. He held two controllers in one hand and one in the other. Then halfway through the song we paused and he took the controller I was trying to use, gave me the other one he'd already gotten to 3 stars, and finished the song up. It was the only way we could get to three stars on all four. It's a rough song!


Stylist
get 3 of the 7 different styles
get 5 of the 7 different styles
get all the styles: twins, energetic, smooth, in rhythm, creative, wild, lazy
NOTE: Most of these you get as you go through normal gameplay. It's just the "twins" one you'll need to get help with.

Also in addition I'll note that you don't get anything at all for crossing 1,000 mojo points. The points just keep counting up.
