"...Nikki Sixx wrote most of the songs for Dr. Feelgood after going through rehab and getting clean and sober, and tracks like “Dr. Feelgood” (about dope dealers who provide the perfect fix) and “Kickstart My Heart” (which Sixx wrote after surviving an overdose) are perfect examples of an artist writing about what he knows. “Slice of Pie” and “She Goes Down” exposed the other side of the debauchery-fueled Mötley playbook. But Dr. Feelgood isn’t just a filth-fueled recipe for a raging party, it’s full of the band’s most focused material and loaded with choruses as infectious as an STD."
