A short section sufficient to identify the work concerned, or to aid in critical commentary of the work.

The sample is of sufficient quality for commentary and identification, but its quality is reduced from the original. Copies made from it will be of inferior quality, unsuitable for "unauthorised distribution" or other uses that would compete with the commercial purpose of the original recording.

Section. The audio sample is used for identification in the context of critical commentary of the work for which it serves as sample. It makes a significant contribution to the user's understanding of the article, which could not practically be conveyed by words alone. The audio sample is placed at the beginning of the section discussing the work, to help the user quickly identify the work and know they have found what they are looking for.
Use for this purpose stated does not compete with the purposes of the original recording, namely the artist's providing a musical performance or recording services to audio or music production concerns and in turn marketing music or audio recordings to the public.

As a sample from a copyrighted musical recording, the sample is not replaceable by free content; any other sample from the same recording would also be copyrighted, and any version that is not true to the original would be inadequate for identification or commentary. Using a different sample would be misleading as to the identity of the work.

Use of the sample in the article is understood to be compatible with Wikipedia non-free content policy and fair use under United States copyright law as described above. Use of this sample outside of Wikipedia may be subject to other terms.
