A rehash is commonly used to refer to a remix of a song by another artist without much or any really
change to the song itself. Seen a lot in pop, rap,
techno music today, and very frequently with jazz and classical music in the earlier years.
Usually easily identifiable by the very similar, or exact-sounding lead,
bass, or
drum lines heard in a song.
Though, take care to remember that some DJ's and artists can very easily remix a song, that uses a lot of the same lyrics and lines as the original. But still add new beats, breaks, and a new feel to the song, and have the song be a legitimate remix.
Pitbull rapped over Nicola Fasano Vs
Pat Rich's '75
Brazil Street', and made a rehash of the song.
'Oh
man! I saw a band do a terrible cover of Led Zeppelin last night!'
'Really dude? I heard a DJ spin a terrible Rehash of Sandstorm last night!'
