Locate the songwriters. Look on the compact disc or find a website associated with the recording artist to find the name of the songwriter(s).
Contact performing rights organizations. There are two major performing rights organizations, American Society of Composers, Authors and Publishers (ASCAP) and Broadcast Music Incorporation (BMI). Both of these organizations will provide information on the publisher. Visit either website and enter the track title. For ASCAP visit ascap.com and for BMI visit bmi.com. If multiple entries come up for that title, narrow your search by typing in the writer’s name.
Obtain the publisher's contact information. You will be contacting the publisher to obtain rights.
Write a letter of interest. Write a letter to the publisher describing why you wish to buy the rights to the track and how you plan to use the music. Include as much information as you can, including your budget, how much of the track you want to use, your complete contact information, and where the tracks will be heard. For example, if you are using the track for a film, note the production as well as the audience size and location.
Send the letter. Wait at least 10 days before following up. Publishers have no obligation to give you permission or respond to your request. If you get no response, try re-submitting.
