I have noticed in My Music, folders of named stuff like <artist> - <album> ... when I select them to get Album Infomation, that it searches the DB backwards, <album> - <artist>.
For instance Drowning Pool - Sinner (folder name) becomes Sinner (Advance) - Drowning Pool when searching Allmusic.com DB, and it does not show any artists related to the name Drowning Pool in the list for me to choose from.
If you want a Debug log file I can post one .. same thing happens with System of a Down - Toxicity
edit - It was the mp3 id3 tags...I changed them, and it found Drowning Pool: Sinner ... but it did search them backwards on that status window when searching.
