[Hemingway's Ghost]

Same shmalzty lyrics, same basic 4/4, same intended audience of pubescent girls with their first crush.

Love Me Do is all Gs and Cs.
Please Please Me is in As with a neat run up to F#m and C#m with an A-B-E bridge.
I Wanna Hold Your Hand has G5s, G6s, D6s, D5s, drops down to an E5 at the verse and stops on a B7, and then breaks into a boxy C-D-G-Em chorus
Can't Buy Me Love is C7s and F7s with drops to Em and A7 in the chorus.
Eight Days a Week is D-E-G with drops to Bm and G in the chorus.

These songs are very different, my friend.

The same song in a different key is still the same song. These songs are all rewrites of whichever one of them was first. Mimeographed pap.
