vagalume is a libre.fm (free version of last.fm) player, and available in extras.

canola2 is available in extras devel, but difficult to install unless you get the right version of libeet1 first. There's a last.fm plugin for canola2 which i've tricked into talking to libre.fm instead.

I've asked in the vagalume thread if it's working for everyone else, and it seems fine unless you have the 720p codecs installed.

it seems to be related to streaming, either video or mp3 . I'd pay more attention to vagalume which is supposed to work out of the box rather than canola which i've hacked a bit.
