If the songs are protected under copyright, then it would violate the law to reproduce the songs on a recording unless you first get permission from the song's owner, usually a music publisher.

Songs written by songwriters outside the U.S. are protected under U.S. copyright laws because of international treaties that grant protection to foreign authors. You can research the ownership of songs at www.harryfox.com, www.ascap.com, or www.bmi.com.

In the U.S., there is a system known as a compulsory mechanical license that permits you to reproduce the songs by paying an established fee -- approximately $.08 per song per recording.
