For syncing purposes, it would be helpful to have setting like "replace artist with display artist"; I love that MB scrobbles to last.fm based on display artist, but the scrobbler on my phone puts out a lot of useless scrobbles like "dolly parton linda ronstadt emmylou harris" that aren't syncing back to my library correctly. I'm trying hard to get more even play distribution by syncing less played tracks, but the stuff that doesn't scrobble correctly never moves out of the list.
