Bluetooth with onboard music (on some newer fitness watches) really sealed the deal for me. After going through a Pebble some years ago, I realized that I didn't actually care about the "smart" features as long as my next watch had excellent GPS performance, Spotify or some other music platform, and an always-on display to tell the time.

Any recommendations? I would love a watch that was dumb as a brick but played music and had gps. Bonus points if it is extremely simple.

I've been loving my COROS. It's quite simple, and the battery life is astonishing. No music functionality though, if that's a dealbreaker for you. I got the APEX 42mm about 5 months ago.

I'm in the market for a similar smart watch/fitness tracker and have settled on the Garmin Vivoactive 4. It hits the sweet spot between a sports watch and a fitness tracker for me, plus the battery should last about a week between charges.

Check out Garmin, tom-tom

a variety of garmin watches have gps, built-in maps and music
