I use old school gPodder to download all the mp3's in the feed.

https://gpodder.github.io/

I've got over 2k v4v songs on my HD 🙂

It subscribes to the feeds and downloads any new songs. That way I always have the latest nostr:npub1mzwcuunusl76z0zczuhh40e8pwh8hspd65pjpse6mvymjwwdhesqrryxc5 and nostr:npub14c7ksq2wln0s9nftjlr0wv2vqpg5xzvw7jezl3whczc0ff2y97eqerl5l2 songs. 🙂
