I ran a search over the forum and couldn't find any topics about this, but:
If there are any users of LastFM's dynamic radio and music profiling social networking site, you may or may not know there is a Linux Mint group
you might like to join. I only found out about this today, and I only recently rejoined Last.fm to have another go
LastFM is billed, as the logo says, a “social music revolution” and fuses two different projects (the LastFM dynamic radio, and the Audioscrobbler music charting tool) into a very nice community and interface. Both Rhythmbox and Amarok, each included in Elyssa and Daryna respectively, are compatible with LastFM, so if you don't use it I strongly recommend you try it out. Also, if there are any users, what do you think of it, and how much do you use it?
