Mines is either Doggystyle, or the Blueprint. These are albums that had beats that were so immediately catchy to me, while really well crafted too. Also, Doggystyle was the first time synths were so spotlighted in a record that I heard, and the way Dre used them was perfect and to me, they never have been used in a better way since. But also, maybe more importantly, these albums were so impactful to me growing up and have followed me ever since.
