Indeed. I'm not expert at all, but the feeling I get from Firepower is: "hey, look... here we go again with super fast metal solos, some good riffs here and there and here comes Halford high pitch screams from time to time because heavy fucking metal, yeah!". I mean... it worked great on songs such as Halls of Walhalla back in 2014. Great song. But I just feel like from 2014 on, every Judas Priest record has a Halls of Walhalla 2.0, 3.0 and so on, just because it worked back then. To sum it up: it doesn't sound fresh for me.
Complain all you want about Maiden, but their albums always sound fresh for me. Right, but that's just my opinion and I think we are going a bit off topic - my bad.
