Why do people hate iTunes?

Honestly.

I often read that iTunes is a mess and it's an awful application. Am I the only who has found that iTunes fulfills my every need? It lets me organize my music into playlists and lets me search for songs quickly. Yes it's not beautiful but does it need to be? I'm afraid that a new redesign might look batter but the functionality will be much worse. I don't stare at the iTunes page when I use it. I pick a song quickly and then go back to browsing the internet, playing games, etc.
