Internally (assuming the track's album tags have the same name, and not X [cd 1] and X [cd 2], and properly have their disc ID3 tags set), it does combine them at the ID3 level and that is accessible by the API. So 3rd party players that support artist-album browsing (as opposed to just browsing the music directories), it will combine them correctly. It can even do this across music folders (e.g., I have split Jefferson Starship's best of across an 80s folder and a 70s 'classic rock' one, but in artist-album, it combined the two perfectly). I know the SubFire suite supports that mode (I wrote it

), but I don't know which other players do.
