Have you heard of Spotify? Spotify is an online music site where you can listen to your favorite songs for free!
You have to stream the songs through your computer (unless you pay $9.95 a month for the premium version then you can get them on your phone and offline) but the free version is really great.
I like it better than Pandora because you actually pick the songs you want to hear, instead of having Pandora pick the songs for you. You can even create playlists.
If you haven’t signed up for Spotify you definitely should!
