I recently switched back to Spotify. Rdio's "web app inside a native app" really kills the experience for me personally, though I'm sure from a dev experience it's a lot less to manage. The app feels slow. Sometimes it refreshes to a blank screen.

But the worst thing - a good part of my collection has gone "unavailable" as they lose music licenses. It's the risk you take when you're subscribing to music, but it seems to not happen as frequently on Spotify - at least for me. On one Rdio mix playlist I had, for example, nearly 40% of the tracks became available. Really a bummer. I liked Rdio's simplicity, but for me personally, the experience was really lousy.

This is valid criticism, and shouldn't be getting downvoted just because people disagree.

I'm a huge Rdio fan and love almost all aspects of its design, but (especially on iOS) I regularly get confused as to where I am and how to get back. A few moment's thought (or just fumbling between panels) gets me where I'm going, but there are simply too many almost-the-same-but-actually-different panels sliding around to be intuitive. It's particularly messy when trying to juggle browsing music with a managing a currently playing playlist.

The android app isn't any better. It regularly refuses to skip tracks (instead restarting the current one), displays different tracks to the one it's actually playing and the offline mode is useless for everything beyond playing music (I can't add a track to a playlist, why?)

There’s definitely an iOS 7 bug where when you view an album, you can only see the first few tracks, as the scroller “snaps” back.

But nonetheless, versus Pandora? I’m leaving my Pandora One sub behind.
