There are 3 rules that apply in creating a great 'mash-up'.
1) the songs you are mashing must compliment each other.
2) they must honor the original songs, yet create something unique out of the 'mash-up'.
3) remember there are no rules: brake & recreate.
Here are three of my favorite mash-ups! Get ready to get you groove on...
"Please Don't Stop Billie Jean"
by Michael Jackson vs. Rihanna
"Alor Americano (Jake Walmsley Bootleg Mix)
by Stromae vs. Yolanda Be Cool
"Finally Down To The Waterline (KMT Mix)"
by Dire Straits vs. Ce Ce Peniston
