It is important to know that there are rights afforded by copyright law are exclusive to the copyright owner(s) as soon as their creation is in tangible form.
You will infringe copyright if you make use of the copyrighted work without the permission of the copyright owner(s) - for example, if you copy or adapt a copyright work.
The best way to avoid copyright infringement is to ensure that you don’t use anything created by someone else. Simple as that.
If you do use someone else's work, make sure you have the necessary permissions – this is usually in the form of a license from the copyright owner(s), which you may have to pay for (you can learn more about licenses here).
There is a doctrine in US copyright law called "fair use" which states that there are certain situations where you may be able to use copyrighted material without a license. However if you want to use any part of a copyright work in reliance on any of the statutory exceptions, you should seek legal advice first.
If you have any doubt regarding the extent of your rights in any tracks, you should consult with a suitably qualified lawyer before distributing the content anywhere.
