 The DJ library advances to the next page when a user scroll reaches the bottom. Page changes return the list to the top and select the first track. Right-click a DJ track and choose Waveforms to generate its cache, prepare loaded decks or the entire DJ library, or force regeneration. Batch analysis runs on a utility worker with saved-cache reuse, progress and cancellation.
 
 DJ waveform generation opens a modal with a coloured progress bar, percentage ring, counts and Cancel. The results stay visible until Done; any analysis issues are listed in the modal.

+DJ library selection supports Command-click for separate tracks, Shift-click for ranges, and Command-A or right-click Select All Songs for all matching tracks across pages. The queue toolbar action adds the selected tracks in library order. Right-click selected tracks to generate or regenerate their saved waveforms or add the selection to the DJ queue.
