Buyout Music (or Buy-Out Music) is another term for Royalty-Free Music. It refers to the one-off purchase of a tune, ditty, bed or effect that has a lifetime synchronization license. Buyout Music can be used as many times as required and no further royalties are paid to the composer.
It is important to note that although the purchaser of the buyout music license has the right to use the track on his or her production, they do not own the music outright.
If you want music that was specifically composed for production use but won’t cost the earth then you can use Audio Network’s extensive music library. More than 213,737 tracks are included from Electronica to Indie. It’s like a Buyout Music library but each track is available for a one-off fee that includes a license for any platform and any territory in perpetuity.
