I’ll say again. never too much.
Time consuming? Of course but music is what we do. It’s to be expected you put alot of time in effort in your job.
Hard to find a track? Not at all, its all about how you organize your library/folders/crates/genre.
I love the fact that I have any song someone asks for, I type it in and its right there ready to go. If I’m at a club and a random song pops in my head and im like “oooh!!” I have it, Selecting a song is no problem. I can play any song that come to mind and on the rare chance I get selection block…. well, thats what your “cheat sheet” crate is for.
