Interested in listening to net radio, with recommendations and such, but don’t want to use paid services like Last.fm? Try Pandora Radio, it’s free and easy to use on your N900 or N9 with a good client that is PyRadio.
While available in the Extras, that version seems to have a serious issue with authenticating, so fetch one from Extras-Devel or Extras-Testing, which works like a charm. Just make sure to disable the repo after you fetched it, unless you actually want them enabled.
If you have a username at Pandora, just type it in with your password and you’re set. If not, create one. Now, you’re free to add stations, and listen to them on the go from your N900!
Liking tracks, adding/creating stations and other things are working on the client perfectly, and, unlike Last.fm it’s absolutely free to use, so why not?
Please note, that for quite a while Pandora has been off limits for non-US residents. While I seem to connect without a problem (and I don’t live in the US), you may experience problems. If you do (try checking by launching pyRadio from the command line), try using Tor.
