XMB music playing

Alright ive tried all of my games 10 in total and none of them let me play music while playing the game

which games let you listen to music while playing the game?`

The only game that I can confirm is SSD HD. You can play songs from your play list by selecting custom tracks. Pixel Junk does have custom tracks but it is not selectable on the demo version.GranReyUno

SSHD, High Velocity Bowling have custom soundtracks but they are accessed via specific in-game menus. Not by pressing the PS button.

MLB the Show 08 allows you to create a playlist and use it as menu music, but only as menu music.

does MGO allow it?AJH_18

Nope
