I have created an Ubuntu package of Last.fm Player 1.0.5 (2.7 Mb). It also adds a Gnome menu icon in the ‘Sound & Video’ submenu (Thanks to Mr_T for help with that). If you don’t know Last.fm you should check it out, same goes for Ubuntu.
If you have any suggestions on things that need to go in the package let me know. I’ll try to keep an up to date Ubuntu package on the site from now on.
