I think he wants music to be added to the library and then start playing immediately like it did in iTunes 7.
Personally, I prefer this new way. Previously, if you had 'Open safe files after downloading' turned on in Safari and downloaded ANY sort of iTunes audio file, it would hijack whatever you were listening to at the moment to play whatever just finished downloading. I do NOT want things I open with iTunes to start playing immediately, and I'm actually surprised Apple fixed this longstanding bug.
As far as all the other nitpicks go, why can't you just ignore them? You guys will complain about anything. If you don't like the 'composer' button, or the Genius sidebar, IGNORE THEM or TURN THEM OFF for pete's sake. Or, you know, stick with iTunes 7.
