Size/track limits for SD card music?

[kick98]

Is there a number-of-tracks limit for music on SD cards? I have a new 2012 C300, and I've populated a 32GB card with several thousand tracks, organized with one folder per band, and one folder per album under each band's folder.

Unfortunately, when I put the card into the car and start browsing it, much of the music comes up missing--some bands are missing one or more albums, and other bands are missing completely.

(All told, I've written a bit over 10,000 songs to this card, taking up roughly 20GB.)
