RARBG really left a big hole in my heart.

I’d love to have everything in FLAC for preservation’s sake, but I’ve settled for Apple’s QAAC. Great quality, small size, universally supported.

Brave because it has great defaults out of the box, and it’s Chromium, so all websites work as intended.
I wish I could recommend Firefox or LibreWolf, but their performance isn’t nearly as good.

I suggest you convert them to AAC with Apple’s excellent QAAC encoder instead. fre:ac can do it just fine once you add the encoder. Much better and more modern format than MP3, and still universally playable.
