What are the best songs from these singers/bands?

[Petzbreeder]

I brought my Amazon Echo Dot with me to my art group today. They want me to bring it again next week.

I asked them if I should make a playlist with songs from their favourite singers/bands. They liked the idea and gave me a list of various singers/bands that they like.

Which songs would you say are the best ones from:

Elvis Presley
Abba
Take That
Adele
Rihanna
Johnny Cash
John Denver
Taylor Swift
Madonna
Michael Jackson
Steps
The BeeGees
The Beatles
Oasis
Meghan Trainor
Justin Bieber
Backstreet Boys

I've never heard of Johnny Cash or John Denver before.
I've actually got a few Justin Bieber songs in mind, so you don't need to give me any of his songs if you don't want to. I'm just copying from the list of singers/bands that my friends gave me. They didn't ask me for any specific songs in particular, except for Thriller by Michael Jackson.

justin bieber - sorry / love yourself
rihanna - rude boy
taylor swift - blank space / shake it off

I've never heard Rude Boy before. I really need to play more of Rihanna's songs.

Funny you should mention those Justin Bieber songs

justin bieber - sorry / love yourself

Those two songs were the very ones I had in mind!
