Thanks maybe you can also look at why knots doesn't pick up all my flac tags either? It's only showing about 25% of my collection which is weird as everything is tagged the same way. I would use MP3 as it seems better supported but my MP3 tags are all over the place and I've been concentrating on my lossless collection the last few years as storage costs are so low these days.

I will look to get on IRC when I have some time.
