Just took a quick look at the list and I'm not quite as down on it as Mike, but yeah, there's a lot of FFs here, and nary a bustout I'm fairly certain. Also, I think "I'm Not In Love" is from '75, not '76, so there's that. And Couldn't Get It Right, while it was released in 76, didn't chart until '77.
(Has DW ever expressed a preference for release date or chart date when placing songs' chronology? Or does he play both sides of the fence?)
ETA: Also, the Tom Petty and the Heartbreakers debut album, while not a huge hit at the outset, is probably one of the best debut albums of the 70s. There are lots of great, great songs on there -- "Strangered in the Night," "Fooled Again," "Luna," to name just three, but there are several others. Couldn't we hear one of those once in a while rather than "American Girl" or "Breakdown" for the umpteenth time this month?
