What other song compilations would you like to hear from R&L?

Personally, I have watched/listened to the Taylor Swift and One Direction caption fails so many times that I sing those lyrics when I hear the actual songs. I've actually never listened to 1D but I know of some of the popular ones and I've seen Joey Graceffa and Luke Conards version of "Kiss You" and I liked it (maybe just because I LOVE Joey lol).

But back to the point.... I think they should do Lana Del Rey and Adele compilations. That would be quite amusing.

Any thoughts?
