I've been thinking on this a lot lately. It's easier for me to seperate the sources of the memes now. E.g. as music is important for me I'll take the lyrics and music as different "memes" enjected to society. And let's take WiH terminology as Zejith mentions;
Theocrat memes - IC memes
Rap music - 70's Rock
Rolling Stones - Led Zeppelin
Paul McCartney - John Lennon
Madonna - Janis Joplin
We have Theocrat-meme icons as Madonna (who I see as the most dangerous type - because she "seems" to be in conflict with organized religion but always makes theocratic music right from the beginning), Michael Jackson, Mick Jagger (still the most money-making group from a world tour, a coincidence?) etc. And IC icons as Jim Morrison (finished his job and faded away), Kurt Cobain (same as JM), Jimmy Page (still around and still making good music).
Of course these are my ideas only, but I always felt something that I could not put into words till now about popular music. Working as an alternative rock radio DJ in 90's, I didn't understand how could people listen to mainstream pop radios, so empty, meaningless and stupid. Now it begins to make perfect sense.
