I'd gotten lazy and been using Pandora but decided to go back to MM with my own collection (which still needs some tag cleanup) but using the GenXML for MM doesn't come even close to getting everything. The results are:
1674 songs
400 artists
272 albums
74 album artists
82 genres
9 playlists (the only one right)
The actual in MM is
138891 songs
10399 artists
9007 albums
2964 album artists
1029 genres
9 playlists
Can't figure out why it doesn't find everything.
Granted I do need to do a lot of cleanup and data scrubbing on the info, but it won't change the fact that there are almost 140,000 songs and it only seems to have found 1674 of those.
Most of my control will be telling it to use playlists and rating of songs anyway, but I still wonder why it missed so much.
