I am somewhat embarrassed to have posed this question as I have just found out that the Last FM player is easily installed via the Package Manager (access via Advance Mode hack)
i'm actually quite interested in this. i downloaded the tar but i have very little experience with this stuff. could you post directions if you got a minute? thanks!
You can then right click on the desktop to bring up a menu where you can select system-add/remove software. You will be prompted for your root password in order to enter the package manager. Here you should run a search for Last Fm, select the last.fm player package and launch the installation.
It was much easier than I had ever imagined and I have been happily scrobbling ever since
