Totally different type of mash up tho. DJ Earworm tries to make a brand new song out of bunch of songs, with a definite chorus and verses. That one you posted is just songs sequencing into each other, no structure or anything. I think DJ Earworm's takes much more effort, and I don't even like his this year
Funny how the last two years are the only times where he's not used the top 25 songs of the year. He's picked his own basically for these last two and both have sucked despite the fact that they should logically flow and sound better. Mess.
