Try before you buy - Update

I found another way to listen to music for free. This time you can listen as many times as you like and you don't need to set up an account. Songza pulls music from many sources including youtube. The problem (as with youtube) is that you may have to sift through a lot of junk to find what you want. There can be many matches for your search that may include covers and idiots trying to show off their guitar skills as they butcher their favorite song. Also, recording quality and volume can differ greatly from one track to the next. It's not a prefect solution but a little patience can be well rewarded.
