iTunes 10

As Apple introduced iTunes 10 on september 1, it started a chain reaction of people whining about the new icon, the replaced traffic lights, the new UI elements and Ping!
It's just like the weather everybody talks about it, but nobody changes it! Let me tell you how you can change most of them so people would stop whining about it and get on with their lives.

Let's begin with the new icon, Apple changed the icon with some good reasons, the only problem is the fact that we got used to the old icon which has been used since iTunes 2, introduced in 2002, thus for most people they changed an icon, the same way we use our money.
This may be hard for some of us, but eventually it will be unavoidable! To make the suffering just a little less painful, I've designed the new icon in the old fashioned way, you can download it here.
The way to change the icon is very easy, to begin, we need to change the downloaded .png file to a .icns file, the best way to do so, is to open up the downloaded icon in Preview.app, than press File, Save as, choose format ICNS and check the Alpha checkbox. You might name it iTunes, as this is needed in the next step.
Once you've done this, navigate to your Applications folder and right-click on iTunes.app, click on 'Show package contents' double click 'Contents' and then double click the 'Resources' folder. Drag your iTunes.icns in there and it will ask if you want to replace the file, say yes, you might need to enter your username and password. That's it, you've changed the iTunes icon!
Do not change anything else in those folders, as it may kill iTunes!

The second most heard complaint is people that don't like the new positions of the close, minimize and zoom buttons. There's a u cure for that too! First close iTunes and open Terminal, you can find it in Applications/Utilities, and type in the following command:

defaults write com.apple.iTunes full-window -boolean YES

When you reopen iTunes, you will notice that the buttons or now horizontal, if you ever wanted to undo this, change the YES to NO in the command line.

And last but not least to you people who don't like Ping,
You can disable it, it's rather easy. Go to the iTunes store, look at the far right side of the black iTunes Store navigation bar, you’ll see your account ID here. Mouse over it to see a little disclosure triangle on the right, click this to see a little menu. “Account” is the top one; click this.
About half way down your Apple Account Information page, you’ll see a panel saying “Ping: On”. To the right of this there’s a button marked “Turn Off”. You know what to do.
Itunes will ask if you're sure if you want to turn Ping off, that's up to you!

-UPDATE-
People who want the old UI back in iTunes 10, can download this file, it's made by Damien Erambert, and changes both the buttons and LCD back to how iTunes 9 looked like.

Now people please stop nagging about the new iTunes and just get used to it, it isn't gonna change any time soon!
