Hey everyone

Lately I've been rethinking how I'm handling my music library. In the past I used to keep everything in iTunes, with playlists, scripts and tagging all done there. Then a few years back I switched to my whole collection on an external hard drive and kept things "sort've" organized with folders (moved away from iTunes as a whole)

It lacked organization but it allowed for loads of flexibility with plug and play on anyones setup. Lately I find myself often jumping on with other DJs and using whatever they're on (either Traktor or Serato)

So my question is:

Is there any software or system, that can allow me to organize my music and prepare it for Traktor OR Serato while still being flexible and having everything on an external hard drive. I miss tagging, and playlists but I NEED the flexibility of being plug and play on any setup
