3 things I'm looking for in a ROM

[derek20la]

hey everyone, i have a sprint touch pro 2 running stock fw (although running the tp2 cleanup add on).
im thinking of flashing to a wm 6.5 rom, but i have a few questions before i go ahead with it.

first, does anyone know of a rom that will let me keep playing music with the phone in standby? currently with pandora and groovefish (also tcpmp), if i press the power button to turn off the screen the music stops. this is unlike what i had with my old mogul (with dcd's rom).

the other things i am wondering, are regarding the IM app and the streaming media app. i like using built-in instant messaging app (Oz?) versus others like Slick because it doesnt constantly use the data connection and drain my battery. also i use the streaming media program to watch tv channels. if not included in any rom, are these at least available in a .cab i can download?

thank you in advance for any answers
