In Windows Media Player 5 or 6 (Can't remember which one I had) You could use an ; to make it so an mp3 showed up under multiple artist. For example, a song tagged as the artist being Ron Carter; Jim Hall would show up under both Ron Carter and Jim Hall in the lists of Artists. I tried using the ; in Rhythmbox 0.11.6 in Xubuntu 8.10, but it didn't work. How do I do this?
