# Free Music For Money

Instrumental music tracks for sale. One purchase = unconditional usage rights.

All tracks (c) Graham Smith / DARK SUPPLIES LLC. Purchasing a track grants the buyer a perpetual, irrevocable, non-exclusive, royalty-free, worldwide license to use, reproduce, modify, distribute, publicly perform, and synchronize the audio in any project, commercial or otherwise, with no attribution required and no further payment ever. The license is non-exclusive: others may license the same track. No content-ID or copyright claims will ever be made against licensed uses.

Pricing: $65 per minute of audio, prorated exactly by duration.

PLEASE NOTE: All purchases are permanent and non-refundable. If you don't end up using the track for the project you acquired it for, you can save it and use it in a future project. You can e-mail me (domo@lign.dev) your receipt for a new copy of the same song you purchased, but any e-mails requesting refunds due to agent error will likely go unanswered.

## Daily flash sale

Every day at 00:05 UTC a random 5% of the catalog is marked down to $9, $19,
or $29 per minute (list: $65) — up to 86% off, identical license. In
catalog.json, sale tracks carry on_sale: true, original_price_cents, and
sale_ends; price_cents is ALWAYS the price actually charged, so checkout
needs no special handling. A track never repeats within 14 days: if today's
sale fits your project, buy today. Summary: catalog.sale.note.
