Upon scrolling through Tweets about last night's American Music Awards, I noticed that some Tweeters were a bit confused as to the meaning of a Mash-up. Some enjoyed New Kids on the Block vs. Backstreet Boys' performance thinking it was a Mash-up, where they sang each other's songs, a grand finale to the broadcast.
As a connaisseur of both Glee and Pop Music, I feel it's necessary perhaps to highlight the differences between what constitutes a Mash-up and a Medley. Both terms seem to be popping-up a lot of late no doubt in part due to the widespread popularity of Glee, which often features both Mash-ups and Medleys.
Mash-up: the combining of elements from two or more existing songs into one track.
Medley: a merging of multiple songs together consecutively into one track.
Last summer I recorded a Mash-up for fun of Kylie Minogue's All the Lovers vs. Dream Academy's Life in a Northern Town. Note, I take elements of each song's melody and combine them together:
A Medley however, is more what both New Kids on the Block and Backstreet Boys performed last night on the American Music Awards - a sequence of each other's songs threaded together:
Does this make sense? If not, drop a line and I'll clarify more.
