Music production is nothing special (same as 98 2000 xp vista).
MTV can use Movie maker, and Vista is better than XP (but after installing Storm Video, the program can't respond, unless you make a DVD, you can get it with DVD maker).
I still use XP to record, and I feel that the drivers and accessories of Vista sound card are very strange (mine is ALC833 sound card).
The CS game is OK, but the ATI graphics card can't open OpenGL for the time being, so I'm a little depressed. I'll wait until the driver is perfect (running the game under Vista is faster than XP, at least the Ghost Warrior 3 Red Guard 2 WinK Simulator Need for Speed 9 I tested is faster).
QQ2007BETA 1 can be used in Vista (open the space link in QQ and close the protection mode of IE7).
3 Audition can be used, but when it is used, the interface will retreat from Aero to Vista Basic (automatic, automatic recovery after closing the program), which is basically useless.
There will be a conflict prompt when installing audio and video, but it can be used, but there is a problem. I used 9.
Everything else is fine. If it doesn't work, just try administrator mode.
(If ATI can't run CS 1.6 in OpenGL mode, it should install QQ in 2007 and turn off the protection mode of IE7. )
