one of the best singles ever.

i believe the Beatles heard Pet Sounds and then decided to experiment and gave us Sgt. Peppers.

"Pet Sounds is regarded by musicologists as an early concept album that advanced the field of music production, introducing non-standard harmonies and timbres, and incorporating elements of pop, jazz, exotica, classical, and the avant-garde. A heralding work of psychedelia, the album furthered an aesthetic trend within rock by helping it transform from dance music into music that was made for listening to, elevating itself to the level of art rock. Author Bill Martin said that Pet Sounds represents a turning point where the Beach Boys "brought expansions in harmony, instrumentation (and therefore timbre), duration, rhythm, and the use of recording technology. Of these elements, the first and last were the most important in clearing a pathway toward the development of progressive rock."[3] In 2004, Pet Sounds was preserved in the National Recording Registry by the Library of Congress for being "culturally, historically, or aesthetically significant."[4] One year earlier, Rolling Stone ranked it second on its list of the "500 Greatest Albums of All Time".[5] As of 2015, Acclaimed Music lists Pet Sounds as the statistically most acclaimed album of all time.[6]"
