Spotify lets you make playlists of any songs of your choosing.
They also have radio just like Pandora that you can listen to based on an
artist, song or album. You can skip or give a thumbs up or down. Another
reason Spotify is better is that there's no limit to the amount of times you
can skip.
After being on Spotify, I have no idea why people do this Pandora thing.
It's like a bootleg Spotify without the best parts.
