Maximum Allowable tracks in Rekordbox

Like eleventybillion.

I'm not sure if there is a maximum, the playlist max is 10,000 songs, but you shouldn't see much of an issue if you're using under 100,000 songs. I know there are a couple of products (like the XDJ-RX) where the maximum is 10,000 for the collection, but some users have been able to exceed that number although there is certainly more likelihood of performance issues when going beyond that.
