Grooveshark is another streaming music app, but with a twist. Besides listening to preset stations, you can create and modify your playlist. You can also upload your own music into the Grooveshark library and add that to the stream you're listening to, and access your tunes on mobile devices using Grooveshark Anywhere. The mobile app is currently available for Android, Palm, BlackBerry and Symbian devices. Using the app, you can browse the Grooveshark catalog via a 3G or WiFi connection.
Grooveshark users are particularly fond of the easy playlist building feature, which simplifies compiling virtual mix tapes for dancing or listening. You can share your playlist via Facebook or Twitter, and make them available offline. With Grooveshark Plus, the paid version of the service, you can be free of advertisements and have access to more customizable features. For an additional fee, you can add this upgrade to your mobile devices with Grooveshark Anywhere.
