Rock References

I went to Keswick on Saturday in the Lake District. I was trying, as well to have a nice day out, to take some pictures that I could post. But, of course, the weather was really, really crap. So... Has anyone ever noticed, among many other subtle things in The Simpsons (the best show on earth), there is a 'Rock Reference' (as I call them) in possibly every episode. By Rock Reference I mean the referral or appearance of a Rock, Metal or Blues song, Guitar, Guitar music, Rock or Metal bands, song name or song lyrics, or Rock Musician. There are a lot of obvious examples like when the bands are actually on the cartoon (Red Hot Chilli Peppers, The Who, Spinal Tap, U2, Smashing Pumpkins, The Rolling Stones, etc.), but there are less prominent references that you could easily miss, like on the episode where Arthur Fortune opens up a new Mall in Springfield and Otto, as he is listening to a CD in a music store, says something along the lines of "This band doesn't sound anything like Judas Priest!" or when Bart gets a Guitar and Otto plays Freebird on the school bus, or even when Homer had a flashback in one episode about how he started drinking beer, there is a Queen poster in the background. As far as I can tell there is hardly any episodes where there isn't a Rock Reference (I don't think the very first one does), but they are very subtle and even though Rock Music is basically my life, I am not a veteran of the Genre (as I'm only 17), so I might have missed many references that older Rockers may not have. Just thought I'd point that out because it's quite interesting I reckon.
