I'm using Musique. It's a pretty simple library-based music player using Qt for its GUI. I don't really have any reasons to recommend it to be honest; I just kinda got stuck on it and am too lazy to try other players. Source: over 2 years ago

If you're dead set against iTunes - Musique is decent -https://flavio.tordini.org/musique. Source: almost 3 years ago

It's open and can be used by many. It has all the podcast I need. It also powers a lot of open source podcast apps like https://antennapod.org/. - Source: Hacker News / 3 months ago

Open source alternative on Android: Antennapod: https://antennapod.org/ https://antennapod.org/download/ Available on Google Play and FDroid. I switched to it many years ago anticipating this exact Google product shutdown, and I've been very happy with it :). - Source: Hacker News / 6 months ago

It's amazing how incompetent they seem in this area. They even shut down another podcast app before your journey began, called Google listen. Luckily, although you might want Google's proprietary music player to access their subscription content, there's absolutely no reason to use a Google podcast app. I am a fan of Antennapod[0], which is available on F-Droid.

Why anyone would use a proprietary podcasting app is beyond me! (Particularly one from Google with basically had a 100% chance of getting canceled....) https://antennapod.org/ is incredible! 10/10, highly recommend! - Source: Hacker News / 9 months ago
