I try to use FOSS whenever possible. Unfortunately while I find AntennaPod to be the perfect podcast app, I don't think there's an equivalent music player. Auxio and Vinyl are great, but have little quirks that cause them to not play nice with Android Auto.
The best I've found is Retro (Metro on F-Droid), which hasn't received an update since April 23, and likely will not again.
Obviously I'm aware that I shouldn't use apps that are no longer actively developed, but I'm wondering if I can buy myself time for Auxio or Vinyl to improve by using Retro and preventing it from accessing the internet?
