Lips

So the easiest way to do this is to get a friend and challenge each other 20 times in total. If each player scores 0 then both players get a win. The important thing to remember is that you DO NOT have to sing the entire song. Once the song starts hit the start button and choose "end song". This will score you a zero and bingo...do it 20 more times and you have 20 wins each. I just got the achievement and it works great! :)

But yeah, basically for those of you who do not want to bother with getting another person, you can basically do this with another gamertag (silver/gold) and another controller on the same Xbox by yourself.

"Here's how:

1. Sign in as your main GT
2. Send challenge to second GT
3. Return to Lips title screen
4. Sign in to the second GT (do not sign out of your main GT)
5. Go to My Lips and accept the challenge
6. Sing the song twice, completing the attempts for the profile
7. Return to the title screen
8. Load up your other profile
9. Go to My Lips and sing the song both times
10. View the results
11. Return to Lips title screen
12. Load up your other profile
13. Go to My Lips and view challenge results
14. Send a challenge to the other profile
15. Repeat steps 5-14 nineteen more times"

Oh, and by sing, it really means start up the song, and quit out as soon as it starts. If both players have a score of 0 on the song, it counts as wins for both players, as I'm sure it's already been mentioned by other solutions.

If you have a friend that has this game play both songs with each of you getting 0 for the song. When you have completed the challenge you both will get a win. Currently doing this now with someone and it actually works. Make sure you both get 0 for the song you are challenging each other against. Also each person will have to load the song so you will have to only play it once and then wait for the other person to challenge you. You can challenge multiple times in a day but once you send a challenge you'll have to wait until they complete it before you can challenge again. Once the other person plays their song you will log back in and get the credit for the win. Also as others have noted below, hit start and leave the song and it also counts as 0 points.

**NOTE do not shake the mic since it adds points, just put it down or don't even turn it on. **

This achievement involves you having to have a friend who is online that also has the game. Once you have your friend you have to take it in turns of inviting each other and accepting the invite. Apparently this is possible to do on one xbox. All you have to do is create a second Silver account and add them to your friends list. Then it starts becoming awkward because you have to sign out of one account into the other to accept/send the invite, and well this goes on back and forth untill the achievement finally unlocks after your 20 wins.

This was achieved is impossible now closed lips servers .... hopefully the other games last longer ... It's a shame it seems the end of the xbox 360
