I'm using the version of MC that's branded as PonoMusic World, and I've found that the software is falsely flagging tracks as duplicate when syncing to the player. Specifically, I've found that with Dave Matthews Band's Complete Weekend on the Rocks, which contains multiple versions of several songs across eight discs, "Louisiana Bayou" is getting flagged as a duplicate. I suspect this is because it's the same track name and track title, but different disc numbers in the album (disc 1 track 5 and disc 4 track 5). It seems like logic needs to be added to check the disc number, in addition to track name and number before flagging as a duplicate.
