I would in a heartbeat. I can't take away the #1 way my family listens to music without replacing it. Sure, they could cast from their phones in the meantime, but we're all used to using our voices and prefer that way most of the time.

If you'd asked me 3 years ago I would have still stuck it out with Goog because of the ad-free YouTube. Unfortunately that's becoming a non issue since most of my content creators have been booted/left YouTube anyway. I think I'd make the jump too now especially if Tidal works well with Android Auto.
I thought it did work with Android Auto. I signed up for the trial, I'll go test later.
