no it doesn't, "I grew up on the Beatles" Meaning you grew up listening to their music "Hmm I used to hate Lil peep but his music grew on me" That is when a sound or genre sounds better Than it used to.
I only knew who Avicii was, I don't really miss him as I didn't know him personally, but it's a shame he isn't here anymore, he was a good person. I only heard about the others when they died so I couldn't care less.
A billboard no.1 and a double platinum selling artist isn't exactly irrelevant.
The fact that you don't know about him doesn't prove anything besides the fact that you are not following the music industry very actively. Not trying to be rude, but he was literally one of the most popular artists in the entire world 2018 and 2019.
