Heres the latest news from the PSN Team:

Music. Where would we be if our ancestors had never learned to master sound, silence, pitch and rhythm? Sweet, life-affirming music permeates almost every aspect of our lives; not least the games we play. Is there a piece of game music that particularly stands out for you, be it on its own merits or for the way it enhances the overall concept?
Some games have beautiful soundtracks and some games, like PixelJunk 4am (which has an upcoming beta you can find out about in the post directly beneath this one) and the upcoming Sound/Shapes on PS Vita have music at the very core of their mechanics.
What does music add to the game experience and what does the future hold for game composition?
Come forth and speak: your views are food to my eyes and ears.
