This is more frequent than you would assume. I’ve neither subscribed to Apple Music nor Spotify for this exact reason: I’m a millenial who would like to discover music.
Another extremely annoying effect is, being 40+, they only suggest music for my age. In “New” and “Trending”, I see Muse and Coldplay! I should make myself a fake ID just to discover new music, but that gets creepy very fast.
