Recently ditched subscription services because of non-stop price hikes. Now I’m on Navidrome with a VPS and using Ultrasonic on my Android for mobile and Android Auto listening. For music, I turn to good old Soulseek and Telegram bots.

Never going back. The control and savings make it all worth it.
