I agree - there is this album "Pornograffitti" from the band "Extreme" which made them world famous. It's a perfect blend of Funk & Rock, but that's not all there is to it - you can hear that it is "more" than the average band sound, and the sound is absolutely unique. After some digging, it can be found that there really is more to the tracks - they went to "extreme" lengths to add subtle details (overtones, inverse melodies, elaborate bass lines) which you cannot hear at first - only when you know, you start to hear those subtleties. My guitar teacher applied some of the concepts to one of the tracks on his band's first album, and it's the only track which really sounds like a hit - the details make it sound epic.
