I only recently discovered Def Leppard after hearing the tracks 'Animal and 'Let's Get Rocked' on the music channels, both of which I loved, so I decided to give the greatest hits album a try. And I was blown away by the new tracks I heard, especially the emotional rock ballads 'Have You Ever Needed Someone So Bad', 'When Love And Hate Collide', their most successful UK single, and the US number 1 'Love Bites'. These are my personal favourites, and I seem to have them on constant repeat. Other good songs include the more mainstream rock songs 'Animal' and 'Let's Get Rocked', as well as the songs 'Hysteria and 'Heaven Is'. In fact all the best songs feature on their hugely successful albums 'Hysteria' and 'Adrenalize', so a hardcore fan might prefer to get hold of those rather than this compilation. I would recommend this album to any fans of Bon Jovi, Whitesnake, Van Halen or any other 80s rock music fans.
