Grooveshark
Number two among one of the websites for music lovers is the Grooveshark.Toplist always describe Grooveshark to someone who is unfamiliar with the site in the same way: it's similar to iTunes in that you can create playlists and save songs to your own library, but instead of having access to only the songs you've downloaded, you have access to every song that has been uploaded to the site. This site's party-friendly features are a major lure, since you can explore songs and add them to a queue without disrupting the current song.
Why hire a DJ when you can share the music selection? Another thing Toplist like about this site (and Soundcloud) is that it's ideal for those who switch between work computers, smartphones, and computers at home. You can listen to the songs you've saved from anywhere as long as you're connected to the internet.
