Important:
You must obtain the proper license to use someone else's copyrighted work. This may include a mechanical license, sample license, or beat license. In most cases, you'll need to contact the original publisher or copyright holder to get permission to use the work. Here are some things to consider.
Mechanical License: You need this to cover or re-record and distribute someone else's copyright. You can get the license you need at tunelicense.com. To determine who controls the original composition rights, you can use the public repertories at songfile.com, songdex.com, or the public repertory of ASCAP or BMI.
Sample License: Depending on whether you interpolate/re-record or sample the actual recording of another composition, you may need to get a sample license from both the master owner and owner/publisher of the composition. If you re-record, you only need a sample license for the composition, which you would clear from the original publisher(s). To determine who controls the original composition rights, you can use HFA, SongDex, or the public repertory of ASCAP or BMI.
Beat Licenses: Beats licensed from platforms such as BeatStars, Airbit, and Soundee may be eligible for publishing administration. Make sure to check the terms of the license agreement and distinguish whether the license is exclusive or non-exclusive. Specific licenses enforce usage restrictions on terms, number of plays, views, and streams. Copyright ownership will likely need to be credited to the original publisher.
Royalty-Free Sample Loops: Generally, you can register a work containing a copyright-free sample or loop from platforms such as Splice, Logic, Garage Band, etc. However, consult the terms and conditions of the specific platform from which you're taking a sample. You can't register a standalone loop or sample as an original and individual song. The loop must be a part of a new song.
