Advise me of a reliable service for downloading music from the Internet for free. I don't want to pay corporations and labels.

I'm not really burnt on doing this either. I decided to try Tubidy and I can happily say that so far it's been fantastic! For me, a complete novice at this, using the service is easy enough: all you have to do is click the "Convert" button next to the video you want to convert, and then choose where on your computer or mobile device you want to save it.
