In addition to Pandora, there's MOG, Spotify, LastFM, Slacker, and Rdio. And probably more.
My only dissatisfaction with Pandora is the limited/repetitive playlist for a given channel.

What is your preferred source of music? Why? What systems are the most intuitive & easy to use, with bigass playlists?

PS - I don't care if they don't stream the Beatles. I'm a Who/Stones man.

I have never used it but I have heard a lot of good stuff about Slacker. I usually just listen to SiriusXM. I will probably try slacker when I get back in the cube.

Stitcher radio is kind of cool. Not sure if it's exclusive to the iPad or not.

Hype Machine is pretty good if you are looking for new-age music. http://www.hypem.com

I like somaFM.

Thanks, guys.

I used to listen the Pandora all the time before it stopped working for non-Yanks. Outside the US, options are limited though I listen to http://www.jango.com quite a lot.

If you have an ipod touch or an iphone, you can pay 10 bucks a month, and make all your spotify playlists available offline. Stops you having to download stuff, and you can get the newest albums in seconds. Once your subscription ends though, you lose the offline music.

I have Slacker on my phone. For $4 a month you get rid of all ads and you can cache up to 20 stations to listen to when your offline.
For $10 a month you can play any song you want on demand.
