Crates are your own folders for organizing tracks — a set for Friday's gig, a stash of peak-time rollers, a venue's vibe. You build them in your Library.
Make one:
Go to Library (top right).
On any track in your Library, click Add to crate.
Pick an existing crate, or type a name under New crate name to start a fresh one.
Manage them: your crates live in the rail on the Library page. Click one to see its tracks, drag tracks to reorder them, and use the crate's menu to rename or delete it. Deleting a crate just removes the crate — the tracks themselves stay in your Library.
Only tracks already in your Library can go into a crate, so bookmark or download what you want first — it'll be there to organize.
