I have a Ps3 Question

If my PSP has songs can i transfer them to the Ps3 and place them in a custom track?

Yes, and yes if the game you're playing allows it (only a few).

I think it's pretty cool how it allows you to do that (especially the part where you can play certain games from your PS3 onto your PSP)

It's possible :L:L
