I like to put Commodore 64 music in my playlist . There's a wicked version of the Doctor Who theme.

Now THIS is a request worth working on!!

Or you just use Sidplay2w and export the SID to WAV and then convert to MP3...
In SIDPLAY:
Press "Settings", "Wav", and change how many seconds you want to record.
Press File, Save as, and change format to WAV.
