i care deeply about open-source software.
i've been looking for an good alternative for shazam for a long time but i haven't found anything. the only good alternative is the one you mentioned first but it's just a modded version of google pixel's now playing.
if you are afraid of data loss, bitwarden is a good choice because it is cloud based and it can also be self-hosted.
i think because many users use anonymous login? anonymous login is like shared credentials and due to many users, it is rate limited. just try to create a dummy google account. don't use your personal google account to avoid being banned.
