Every song sounds the same for these guys. It's obviously working since their fanbase is a bunch of diehard DMB fanatics, but the rest of us aren't as interested.
Queen
The minds of the guys in Queen are easily the most creative and genius. Sadly, the band became extremely oversaturated. Even diehard Queen fans will call them overrated just because of how top music executives treated them and their brand.
Queen quickly became a staple in a bandwagoner's world. Mainstream brands commonly put their logo on t-shirts as a selling point. The band released 14 albums (way too many) altogether until Freddie Mercury died. They did try and get back together with another singer later on, but that proved to be a bad move.
AC/DC
A lot of old heads will tell you what AC/DC did to rock and roll in the '80s. Most would agree that they killed it. They were basically a result of industry standards and what executives wanted to be profitable.
