Spotify vs Rdio

I've been pouring over this blog post from GadgetReview comparing the two most popular streaming services, Spotify and Rdio.

I'm tired of listening to the drool that the state broadcaster forces upon it's subjects, and I don't have the interest or wallet to build my own collection. Streaming seems perfect, and it's undoubtedly the future.

Spotify streams at a slightly higher quality. Their libraries are both incomplete. Rdio's interface looks cleaner, and it has a web app. They both have stupid names.

I've played with Spotify and I've just signed up with a free trial from Rdio. I guess it's going to come down to which has the biggest Biffy Clyro collection.
