Is there anygame like www.projectrockstar.com but that doesn't need like so much turns or doesnt have a turn system. Cause man, u take like 3 actual days just to write a song then record it.

You have Popomundo (http://www.popomundo.com). It takes you a while to reach the full potencial of your music, but you can choose to end it earlier, and as you progress in the game, your musics get better. You are the main character, it's time based and it is very addictive. You can learn more about it in the Popomundo FAQ (http://www.popomundo.com/Common/Faq.asp). =)
