When I listen to "Loaded" I generally listen to the whole thing.
Wikipedia has a pretty interesting entry on it:
By 1969 the MGM and Verve record labels had been losing money for several years. A new president, Mike Curb, was hired. Curb decided to purge the labels of their many controversial and unprofitable acts. The drug or hippie-related bands were released from MGM, and the Velvets were on his list, along with Eric Burdon and the Animals and Frank Zappa’s Mothers of Invention. Nonetheless MGM insisted on retaining ownership of all master tapes of their recordings.
Atlantic Records signed the Velvet Underground for what would be its final studio album with Lou Reed: Loaded, released on Atlantic’s subsidiary label Cotillion. The album’s title refers to Atlantic’s request that the band produce an album “loaded with hits”. Though the record was not the smash hit the company had anticipated, it contains the most accessible pop the VU had performed, and several of Reed’s best-known songs, including "Sweet Jane” and “Rock and Roll.”
Though Tucker had temporarily retired from the group due to her pregnancy, she received a performance credit on Loaded. Except on a few songs, drums were actually played by several people, including Yule, engineer Adrian Barber, session musician Tommy Castanaro, and Doug Yule’s brother Billy, who was still in high school.
Disillusioned with the lack of progress the band was making and pressured by manager Steve Sesnick, Reed decided to quit the band in August 1970. The band essentially dissolved while recording the album, and Reed walked off just before it was finished. Lou Reed has often said he was completely surprised when he saw Loaded in stores. He also said, bitterly, “I left them to their album full of hits that I made.”
However, Reed was particularly bitter about a verse being edited from the Loaded version of “Sweet Jane.” “New Age” was changed as well: as originally recorded, its closing line (“It’s the beginning of a new age”) was repeated many more times. A brief interlude in “Rock and Roll” was also removed. (Almost three decades later, the album would be reissued as "Fully Loaded" with the edits restored and all versions included.) On the other hand, Yule has pointed out that the album was to all intents and purposes finished when Reed left the band and that Reed had been aware of most, if not all, of the edits. The few weeks between Reed’s departure in late August and Loaded’s arrival in the shops in September of the same year also would have left little room for the whole process of editing, reviewing, mastering and pressing.
