Last month, Rdio unexpectedly announced that it's shutting down service and handing over the keys to Pandora. Existing subscriptions are rapidly dying off, which means it's time to lament all the poor life choices you made with Rdio's help. On a goodbye page, Rdio has provided a link to export your favourites, playlists, downloads and comments as a handful of different formats, so you can transfer over to your new streaming service of choice. There's also a handful of statistics, so you can get all nostalgic thinking about your first song, or the most popular.
I never used Rdio all that much, so I'm embarrassed to say that both of those for me are Kelly Clarkson's Since U Been Gone. In hindsight, not such a bad way to say goodbye.
