Thank you everyone for offfering help. I went through a 6 hour nightmare yesterday as not only did installing iTunes 11 ruin my music experience, I foolishly synced my iPhone 5 with it. After I realized I just cannot live with iTunes 11, I tried to downgrade. The biggest problem I found was that for some insane reason I had no iTunes Library.itl since 9-14-2012. I had done not insignificant playlist creation since that date. Plus, I was getting -42408 errors upon iTunes launch and my iPhone 5 was not restoring to its previous state but one from months ago (losing texts, etc.) I will try later today once more to downgrade and I guess live with having to manually recreate my playlists from my iPhone (before syncing the phone with the downgraded iTunes).
Perhaps the biggest complaint I have about iTunes 11 that I have seen no one mention yet, is that if you click on Music in any view, and select a song or artist, then go and click on a playlist, then click on Music again, you are automatically brought back to the very top of your music collection (for me AC/DC). So you are constantly forced to scroll and search every time you want to listen to music (unless I only ever listen to AC/DC again). In iTunes past, you could click on an album (in beloved cover flow), drop a song into a playlist, play a song in a playlist, play a podcast, etc., etc. and then when you did click on Music again, you were taken right to where you last were still showing that album, which I never realized was as convenient as it was. So this to me perhaps more than anything else makes iTunes 11 useless.
I too of course miss cover flow which was how I browsed my music collection, and iTunes DJ and I never even knew about the function of having people vote on songs etc, I just liked having a quick view of random songs from my entire collection.
If anyone thinks there is a way I can downgrade to iTunes 10.7 (I have the .dmg on hand) and put back my iTunes Library.itl from 09-14-2012 but still keep my playlists as they exist today, please let me know.
The other variable is my iPhone which did not back up and restore properly and since trying to fix things last night it made like six backups in a row, I fear I may have no pre-iTunes 11 backup left to go to meaning losing several months of texts and contact updates. The phone is back to being how it was at 6pm yesterday which is great. The only issue I have is I have to live with iTunes 11. I do not know if I should risk going through hours of nonsense again like I did yesterday just to try to get back to iTunes 10.7, knowing eventually Apple will require the latest version of iTunes to get full iPhone functionality, etc.
