I had recently posted regarding a few issues I was having using Rune and the manner in which my music is tagged. The post is here:
http://www.runeaudio.com/forum/post15731.html?hilit=%20album%20artist%20#p15731, if you're curious. Although the post got a few views, no-one had any suggestions for me - no big deal. I've kept using Rune and have come up with a workable (for me) solution for one of the issues I was having. I thought I'd share it here in case someone else finds it useful.
The issue was using Album Artist as a means of organizing (and finding) my music within Rune. The problem with Album Artist is that it isn't an official ID3 tag and different players/ music managers treat it differently. MPD seems to ignore the tag. However, I've found a way use Album Artist that serves my needs and avoids the unofficial tag issue. I have organized the folder structure of my library as AlbumArtist/Album/tracks. Browsing the file structure via the Rune Library Network Mounts or USB drives gives me the view I need to find my music in the manner I'm used to.
I can imagine a few "Duh"s in response to this suggestion. So be it. It took me a while to realize the solution was right in front of me all along. Maybe this post will help someone else.
I use Foobar2000 to organize my music and play it on my desktop PC. It was very easy to use Foobar2000 organize my files as I described above.
