How do I skip songs by holding the volume buttons?
 

So, a while ago I was able to listen to music and skip songs forward and backward with the physical Evo volume up/down buttons. Well, a few ROM flashes later I am not able to do this anymore.

I dont know if this has anything to do with it but right now im running FreshROM and I have run Cyanogen 6.1 in the past. Might have been when i was able to do this, not sure. The only music programs I use are the stock android music one and WinAmp.

Anyone know how I can do this again? It would be awesome to skip songs while not having to take my Evo out of my pockets.
