This is a sound sample from a commercial recording. Its inclusion here is claimed as fair use because:

1. It illustrates an educational article that specifically discusses the song from which this sample was taken, as well as the band that performs it.
2. It is a sample of about 30 seconds from a much longer recording, and could not be used as a substitute for the original commercial recording.
3. It is of a lower quality than the original recording.
4. It is not replaceable with an uncopyrighted or freely copyrighted sample of comparable educational value.
5. It is believed that this sample will not affect the value of the original work or limit the copyright holder's rights or ability to distribute the original recording.

1. It is used for educational purposes to identify the song that is discussed at length in the article.
2. It is used in an article that discusses specific elements of the song's background and composition and provides commentary on these elements where prose cannot.
3. It is used to illustrate the song's positive impact on the artist's recording sessions where prose cannot.

1. It is used in a section providing commentary on "One". The sample is used to supplement the article and depict the song's composition, both musically and lyrically, where prose cannot.
2. It is of a chord progression played on guitar, which was a breakthrough in the album's recording sessions. The sessions had been plagued by conflict and limited progress, and the group was considering breaking up. The song's writing began with this chord progression, and it was a pivotal moment for the artist and the completion of the record, as it changed the artist's outlook for the better.
3. It is of one of the record's most enduring songs, as many critics have called it one of the greatest songs of all-time.
