Query: Hard rock at the best

"Hysteria" was such a smash that was impossible not to listen to these magnificent songs on the radio.The album spent almost two year at the top of billboard 200 and it's absolutely one of the classic '80's album.The title track is a stupendous slow song;"Armageddon it"is a powerful rock tune that brand your mind;"Love bites" is a love song that moves your heart and "Pour some sugar on me" is another example of great songs.i also suggest "Pyromania"another classic Def Leppard.
