Alright this is an idea that probably only I would like, and if I was a coder I would do it. Since the mp3 plugin came out I found it cool how if you look at a video at the same time the music speeds up by half, I thought it would be a cool idea to release a homebrew that you can have your mp3's go faster or slower.

EDIT: Well that was funny, the Ruckus player has what I want
