OK, so I'm also new to the site, but I'm blown away by the original post... Is Tom Petty still alive, and why would anyone think that he's at the pinnacle of musical composition? The suggestion that film music is inadequate or inferior because it's not in the Top 40 is ridiculous; Bentley's don't sell anywhere close to what Ford pickup trucks sell, but which would you rather own? Popularity is not necessarily an indicator of quality. I also deny that John Williams writes simple tunes. If you listen to the strings, horns, woodwinds etc. separately, there's a lot of different things happening that sound amazing when combined. At best Tom Petty had to do 1 set of drums, a guitar, base guitar, lead vocal and backup vocal. Tom Petty's stuff sounds pretty much the same doesn't it? You can't say that Star Wars, Close Encounters, Schindler's List, Minority Report and Catch Me If You Can all sound the same. You know what you get when rockers try and compose film music? You get the scores for "Dune" and "Ladyhwake"...
