For my second post of ubuntu battles, I'm going to delve back into historic battles (last night) and talk about how to get mp3's to play in Rhythmbox. The first time I did it, it was bizzarre and involved lots of messing about, but now I find the following AMAZING program...
Immense. So easy.
The best thing is, Rhythmbox has AudioScrobbler built-in, so if you are a last.fm fanatic, you only have to enter your username and password in Preferences>AudioScrobbler.
Note to self: Actually RUN the EasyUbuntu program after you download it, before you wonder why mp3's are still not recognised. Doh.
