I publish on my blog as often as I can and I have for quite some time finished my blogs by adding a “Song of the day” and finished my posts with an embedded Spotify play button.
I would much rather have this option but from ListenBrainz.
If you press it and have Spotify integrated it would play through Spotify.
If not it would simply display the track and subsequent release published on MusicBrainz.
I think it would greatle boost the interest. Things like this should be free for all.
