Strange. I was the biggest Rdio advocate until it just flat out didn&#x27;t work on my MacBook. Tried uninstalling and reinstalling with no luck. Support couldn&#x27;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.
