Yes, it seems ok.
Apart from the names displayed on the “Linked MusicBrainz recordings” sections on acoustid.org, though they link to the correct tracks. Looks like some stale data. I’m not familiar so I don’t know when (and if) it will get updated. (edit: the names got updated. everything is good now.)
Also, may I ask how I could make such MB-AcoustID links by myself, for future needs?
