Does not work with Yandex Music and especially with Moya Volna.
Не работает с Яндекс музыкой после того, как там всё обновили. На Github уже пользователи уже создали темы, но всем пофиг.

Does not work on Amazon Prime Music. Does not even recognise that site. So yeah extremely annoying and useless.

does not work with youtube

(3* Rating) It works, but often with updates it resets manually entered song details. Sometimes a song may not be formatted right, so you often fill your library with silly looking titles. It used to not scrobble every single video I watched, only music, but suddenly this feature is gone?

(Updated: 2* Rating) After a recent update it has once again reset song titles with the addiiton of some Artists randomly show as "*Artist* - Topic" and manually entered songs messed up again.

Generally a convenient add-on but has not been working reliably with Apple Music for months

Ha dejado de funcionar. No reconoce ninguna canción, solo muestra una ventana en blanco. Al reinstalarla el icono de la barra aparece transparente y al pinchar no hace nada. Una pena
