I’m amazed I haven’t shared this on here before. In my humble opinion, this is the best mashup song in the history of mankind, only run close by the Bee Gees/Shakira/Britney mashup that was ALWAYS played on The Box (ah, memories). Many mashup tunes don’t flow properly but this rides the beat so perfectly, it’s insane. Enjoy!
Also just realised that Rolling in the Deep is proper mashup fodder, as there is another fantastic one where Adele is fused with Sweet Dreams by Eurythmics. If you haven’t heard it, step on it!
