I’ve been a long time fan of Grooveshark for many reasons. It’s not a perfect internet radio but it’s pretty awesome. For quite a while now, I’ve been hearing that Grooveshark is working on an app for the iPhone but it seemed like it would never arrive. Finally, on August 5th, it did. With Grooveshark Mobile, you can do the following:

• Listen to any song you want – anything at all whether you own it or not
• Create playlists of all your favorite songs and keep them with you both on the computer and on your phone
• Enjoy customized radio stations based on the music you like, much like Pandora
• And here’s the kicker: DOWNLOAD any songs or playlists to your phone in offline mode for listening to any time you want, with or without internet connection

So that’s pretty rad. But THERE IS A CATCH. You get all of this free for 30 days but if you want to continue with it after that, you have to become a pro member for $3/month. Not too shabby for that price, though. I’m a total cheapskate and I think I’ll do it. Plus, as a pro member, when you use Grooveshark on your laptop or desktop there will be no ads. Nice.

About Offline Mode: In order to download a song for offline mode, simply click on the Details (li’l right arrow) for the song or playlist you want to download and select “Make Available Offline”. Then you’ll see a progress bar of the download underneath that song or playlist.

With offline mode, you’ll want to leave it disabled most of the time that you have an internet connection (3G or WiFi) and enable it only when you don’t have a connection because you can’t stream music or browse through un-downloaded playlists while in offline mode.

So give it a try. Hopefully you’ll enjoy being able to listen to just about any song you can imagine. Long live Grooveshark!
