Deletion of 3 (Suburban Kids with Biblical Names album)

Comment: I'm rather confused, https://en.wikipedia.org/w/index.php?title=3_(Suburban_Kids_with_Biblical_Names_album)&oldid=710562683 there was a source present in the article prior to the nomination, and its still there. And it's AllMusic, a reliable source per /SOURCES, that covers it in good detail. I'm concerned how three people now have stated "unsourced" as their deletion reason. How closely are we investigating here
