I'm rather hyped that I can play my own music on the Vita, but I wonder,
what songs stands out for you and makes you go: " you have to play this while racing."

I have seen Vojeet made a big Zip file with a bunch of songs, <3 em, and the project is great,
Tough this is 2012 and perhaps you have gotten some new favorite?

Here is my top five of songs so far.

#1 Knife Party - Destroy Them With Lazers :: MP3 Link
#2 Nicky Romero - Toulouse (Original Mix) :: MP3 Link
#3 Ralvero - Xtreme (Original Mix) :: MP3 Link
#4 Camo & Krooked - Breezeblock :: MP3 Link
#5 Shock One - Polygon [Ft. Reija] :: MP3 Link

Link yours here and I will try to make a Zip with all the songs for easy download.
