Rolling Stone has posted an article on the current frequency of interpolation (the act of taking a snippet of an already recorded song and using it in a new way) in modern pop songs. While interpolation is nothing new in the music business, it seems like its happening more and more. Have you heard a song with a sample and you can’t remember who wrote it? You can head on over to WhoSampled, the largest database of music samples and interpolation listings on the internet to find out.
