I have tried them all. I have been using Pandora since the early days, and I pay for the premium Pandora service. I tried, for at least a month each and often more, all of the old guard of the streaming music services. Rhapsody. Napster. Slacker Radio. I owned a Zune HD, and subscribed to Zune, and when I bought my first Windows phone, I subscribed again to give it a second try. When Spotify got hot, I tried it for a while, sharing playlists and music. I have tried Rdio and Last.fm. I’ve spent time on Turntable. For a couple days, I even used Ping. But there is one online music service that is my favorite by far. I’ve been using it for almost a year, and it’s actually gotten better since I started. I listen at work on my desktop, on my smartphone while I’m exercising, and in my car on my stereo.
