The best feature about the Vita that doesn't always work.

[ps3-sales!]

Music playback during games. I love it!!! Such an underrated feature, and perfect for those smaller games on the go like Sine Mora and Super Stardust. But why doesn't it work with Psp games? Or better yet, some smaller games like Hotline Miami (although the soundtrack is epic anyway).

Curious to see if anyone knew anything about this; be it Sony previously announcing a fix or saying it is what it is. 

I want to listen to Eminem's new album while playing God Eater Burst!!!
