This feels a little like the old “if you could only listen to one artist for the rest of your life” question but I feel often bands perform better in concert, and would be more exciting than other classic bands.
Personally, I would choose Van Halen, not my favourite band, but have a much happier sound and lyrics, compared to other bands who would just make me depressed. It would also be hard to be bored of that energy.
Hiya sweet tooth yup van halen were good but I don’t think I would have wanted to listen to them everyday the old classics were the best
Mika had great energy
Now you going to be singing that all day 
Good, I was successfully brainwashed.
Evil laughs I bet you play it more than once
Still playing on loop
I’m going to get you addicted to mika
OMG now I can’t get that chorus out of my head
I’d go with Coldplay,their songs hit all the moods, from chill and emotional to super hype. Plus, their concerts are always a whole experience with crazy visuals, lights, and that magical vibe. Feels like even if you watched them forever, you’d never get bored.
