Literally applicable to Adele

Interesting

She didn't use RITD as an example for nothing

Talent

Good points. I don't necessarily agree or disagree with the last point tho.

Hyperbole. No one knows what songs people will be playing in 60 years. It's just as likely they'll be playing All About That Bass as it is that they'll be playing We Found Love.

Part 4 is literally the truth. Just about all the great songwriters say that (not saying she's one of them)
Everything has already been written so you have to crack the code of telling the same old story in a new and exciting way.

Countless songs out there with the same overall theme as Someone Like You and the rest of the songs on 21.
