Yeah, I just switched to rdio and I love it. The interface is so clean and slick. It's a lot less buggy / unreliable than Spotify imo. It's such a pity.
Strange. I was the biggest Rdio advocate until it just flat out didn't work on my MacBook. Tried uninstalling and reinstalling with no luck. Support couldn't do much for me. I ended up moving to Spotify and while I agree that Rdio has a superior UI, Spotify worked consistently on my machine. Plus, their mobile app, especially offline playback, is a godsend on long trips.
