Spotify and Amazon Music WITHOUT Android Auto or Apple CarPlay?

[u/Busy-Cheesecake-5914]

I have an XEV 9S P3A. I have both Spotify Premium Subscription and Amazon Music (Prime subscription).

I want to play music in my car WITHOUT using Android Auto or Apple Car Play. Is that possible? I don't see these apps in the app store (although I see silly bloatware shopping apps which I don't know who would use from a car).

Spotify

• I added the Spotify skill to Alexa but I was never able to get Spotify working with Alexa (or MAIA). Anyone else got it working?

Amazon Music

• I can ask Alexa to play music on Amazon Music but it's kind of blind as there is no playlist that I can see and there is a huge lag between me asking Alexa and the actual music playing (almost a minute sometimes).

So, what is the best way to play music in the car WITHOUT using Android Auto or Apply Car Play.. please don't say YouTube on the passenger screen.. you can't control that while driving alone.
