I also have an old P4 running my NAS with a 1TB hard drive which is why I can get away with my ubuntu/web/Ampache server being a 4.7gb virtual machine. Plus, the same folder that is called 'music' servers my Ampache server, itunes and any other media player/devices/software I use. Recreating media folder over and over gets old and time consuming.
I always forget about the radio feature since I don't use that either. I prefer xmplay as my player of choice for .pls and .m3u playlists. Small and low on resourcess.
