I use Rdio instead of Spotify because of its radio feature<p>Contrary to what the article was saying, whenever I started one of those automatic playlists based on an artist or something, Spotify would seemingly play stuff at random. There would be some coherence, like "songs using the same language", but it would jump wildly between slow, fast, folk, rap, dub, and what have you. Really, it did not work at all for me.<p>In contrast, the Rdio radio stations work really well for me. You can base them on songs, albums or artists and they will stick to that genre within reason. I had some of those playlists running for days on end without them getting annoying or repetitive or veering off genre.<p>This has become my most used feature of Rdio.<p>Well, and then there is the thing about Spotify not being available here. But that is really not something that would stop anyone in the HN crowd.
