So, I really love 4shared but, I am really into lots of underground bands, so 4shared isn't really good for that because it doesn't have a expansive collection of music...

I also tried Bearshare, but you have to pay after a while, and it also didn't have many of my favorite indie bands.

I need something that convert easily into iTunes (because that's where I sync my music) or I can download the songs/albums straight into iTunes, or, is compatible to easily sync into an iPod/MP3.

Something that has a large range of music including underground bands, is easy to use and is free are all musts...

Please haaaalp
