I've noticed that some albums or tracks (a small percentage) which I add to my library don't appear in the New Albums playlist, although they do immediately appear in their respective genre correctly.

I really dig and most frequently use the New Albums playlist feature, and so it peeves me (!) when I have to go searching into the genres looking for an album I've recently added, as sometimes I don't immediately recall the correct genre which I've assigned...

Most importantly, this issue I've noticed only occurring with some MP3 files, and ALL of my content is added to my primary library in precisely the same manner with all relevant metadata intact & correct.

I've been trying to figure out why its unique to MP3's though (and very few at that)...and why they do appear in their genre but aren't shown reflected in the New Albums (or New Tracks) playlist.. any suggestions as to what could be going on are most appreciated ;-)

Btw- I'm running 4.5 (1) on OS X.

PPS- Asset UPnP is awesome, really love your work.
