Wait… so you stopped using rdio because you didn't like the design, but you chose spotify? ARE YOU BLIND MAN?
I did not like Rdio's re-design at first, but it has grown on me more than I thought it would.
Spotify's other killer feature is local sync on the laptop. I'm usually dependent on crappy hotel/cafe wifi and Rdio just chokes.
Spotify had a terrible Android app for a while, so I switched to Rdio. Then Spotify really improved their app so I considered them again, but now Rdio's app is even better. Hmm...
Also, Rdio has a "family plan" type thing. My wife and I both have accounts, so we get a discount.
