A huge percentage of hip-hop and electronic music is essentially this, sampling and remixing segments of other songs. Old school DJs since forever have been known to keep absolutely massive libraries of records going back to the beginning of sound recording, and to actually listen to them constantly - always searching for new and interesting sounds that can be used in new music. I always found this aspect and type of music production so interesting - at this point in human history, more sounds and music have been made than almost anyone can listen to and appreciate on their own, so in a way DJs and remix artists are like archeologists, digging through a century of recordings to uncover, polish, and present a rare gem of sound in a new setting.
