Listen to music for free

I like to preview an album before I buy it. Websites like Grooveshark and Spotify allow you to “stream” music-–to listen to it in your web browser without downloading any files. Grooveshark is completely free but doesn’t have a huge selection. Spotify has a wider selection, but requires you to either pay a monthly fee or listen to ads every few songs. Either way, make sure to support the artists you like and buy their albums!
