So I've started a HUGE reorganization of my music, and I'm doing it with Smartcrates in SSL. I'm using the "Grouping" tag for anything video and the "Genre" tag for anything MP3. I figure that this will be easier for me than trying to have separate crates for audio and video -- instead, if I DO need to search for an MP3 in a certain genre, I just have to add a line to the smart crate instead of having all my MP3s polluting up my video crates.
Other than codes (which I know some DJs use for their crates) does anyone have a better way? I'm all ears.
