Your Library is the home for everything you've touched in Digital DJ Pool. Open it from the top right of the web app at app.digitaldjpool.com.
It's split into tabs:
Downloaded — your full download history. Every track you've pulled, newest first. Yours to keep forever, even offline, even after you cancel.
Bookmarked — tracks you saved to come back to, without downloading them. Your shortlist before you commit.
Listened — what you've previewed, so you can find that track you played earlier but didn't grab.
You'll also find your Crates here — your own folders for organizing tracks into sets. See How to make a crate.
