I’ve become a huge fan of Rdio.com (pronounced arrr-dio). Just about anything I want to listen to is nearly always available to me and – to boot – I am discovering a ton of new music through the service. For $10/month, that’s not too shabby.
One of my favorite features is that you can create and share playlists; below is what I’ve been listening to at work for the past month or so. I’ll be adding to this playlist over time, so feel free to check back.
