What happens when you combine two huge hits released 28 years apart? Find out below!

Unfamiliar with mashups? They are the mixture of two very different things, often songs of different genres being combined to create a blended and unique sound. They’ve become pretty popular over the past few years, and it’s been fun seeing the creative efforts and unexpected pairings.

"Eye of the Tiger" by Survivor was released in May of 1982 as a single from the rock group's third album. The song was written for the movie Rocky lll at the request of Sylvester Stallone and went on to hold the number one spot on the Billboard Hot 100 chart for six straight weeks.

"Rolling in the Deep" by British songstress Adele was released in November of 2010 off of her second studio album 21. The song was written by Adele and Paul Epworth and won a Grammy for Record of the Year and Song of the Year. It stayed at number one one the Billboard Hot 100 charts for seven straight weeks.

This is a fun mashup, but you'll have to wait until 49 seconds in before hearing Adele's vocals.
