Library: tracks & uploads.

Drag + drop on /library, or click Upload. WAV, AIFF, FLAC, MP3, M4A — 500 MB max. We store the original byte-perfect in cold storage and transcode a 320 kbps proxy for the player.

ID3 tags are read on upload — title, artist, album, year, genre, BPM, ISRC, lyrics. The display title strips boilerplate (label codes, "[Master]" suffixes) for the EPK / presentation views; the original filename is preserved internally.

Top of the Library: a search box (matches title, artist, filename, ISRC) and a Filters disclosure for status, artist profile, and any custom fields you've defined.

Search is unaccent-aware: typing "beyonce" matches "Beyoncé."

Select rows with the checkbox column. Shift+click for ranges (Cmd+click works too). Once you've selected one or more, the top toolbar reveals:

• ·+ Add to collection N — opens the modal to drop the selection into a new or existing collection.
• ·Edit selected N — bulk-edit shared metadata (artist profile, custom fields, etc.).
• ·Delete N — soft-deletes the selected tracks. Recoverable from trash.

On the track detail page (/tracks/[id]) the Pro Catalog panel surfaces every field we read: album, year, genre, BPM, track number, ISRC, lyrics, composer, writers (list), internal notes, client notes. Click Edit to update.
