Pandora and Youtube are great suggestions.
With Pandora you input an artist and it plays 1 song from that artist, and then branches out with similar artists to the original, then similar to the 2nd group, then similar to the third group, etc. (not quite that linear but that's the idea). You can also like or not like and it will react to that.
iTunes is also pretty good. It's free from Apple. Plug in an artist and listen to samples, and it will give a "what others have bought who have bought this artist" to give you other ideas. Of course you can buy music.
