Soundclick, it is very secure and they don't keep sending you junk emails every 5 minutes like some of the others do. Revernation is ok but you get a lot of sign up for Junk email ... soundclick I never get that type of stuff ... What I like is you can also see how many people played or downloaded what song so you can know what tunes people seem to like or dislike. They also rate your music along with others in the same genera so that helps also. The only thing is to sign up you should have at least one of "original content" as that is what soundclick really is about.
