Previously, a sound recording could not legally be a work for hire because it wasn't in any of the statutory categories. Sound recordings have now been added to the list of categories of works that are capable of being work for hire. RIAA-sponsored "technical amendment" to a Congressional bill makes recorded music "works for hire" under the 1978 US Copyright Act. Now Under Section 101 of the Copyright Act, a work that is specially commissioned (read, not created by a full-time employee in the scope of his employement) can be a work made for hire and if there is an agreement signed by both parties which says it is a work made for hire.
