I don't know if this a bug or feature, but I noticed how MB would export embedded lyrics as text files and place them in the album folder named after the corresponding track's filename upon the initial playing of any track from said album. The embedded lyrics are wiped from the process.
Now, I'm rather ambivalent to embedded lyrics (I know some of you here care about them), but I do instruct minilyrics to only download time-synced lrc files and I prefer not to have lyric text files populating my album folders. Am I missing a new setting that corrects this behavior?
