Black Dog (song)

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

The sample is of reduced quality (and or timespan) compared to the original, yet of sufficient resolution for commentary and identification. 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 image 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. Purpose must be stated here.
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 copyright 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.
