A little catch up to do:
Petty - falls into the same category as my Bowie/Prince comments earlier...artists being lost that I do not see replacements for in the current music scene/environment. DTT is a classic, though I gravitate to the less played songs (may be sacrilege, but "Refugee" was never one of my faves). Got heavy into Petty around "Southern Accents" through "Into The Great Wide Open" and I do think he has more diversity in his catalog then some give him credit for here. Glad I saw him live during this period (as well as once when he was backing Dylan)....killer band (though he could have used a little more variety of set list and let the band strecth out a little bit more). RIP
Springsteen - being NJ based, he is ubiquitous. Do love the Boss, but not in a worship way. Killer live show, and appreciate that he followed his muse in exploring some other mediums (though not always a fan of the exploration). BTR was my introduction to him and what a song cycle. Just not a bum one in the lot. From here to "The River" he did no wrong, then he reached for mass popularity with Born In The USA. Sort of lost touch until The Rising, which, being "local" to 9/11, just resonated once again with me. Don't know if you need to be from around here to understand, but encourage those who are open, but unsure, to take another look.
Sabbath - was quite anti-metal in my youth, but, with the grunge movement capturing my ear, it brought me to go back, explore, and appreciate the genre. That said, while I appreciate Sabbath, and their legacy, it is not in any regular listening rotation.
Tull - blind spot for me...my soon to be 17 year old had a Tull phase (how I don't know...think it was when he was buying cheap used vinyl and guess there was a lot of Tull available). Did not catch me any more the second time around than the first. Can appreciate a few of the hits, but not much more beyond that.
