It looks like there are a bunch of iPod Touch users that keep getting a screen prompting them for a January Upgrade. When clicking on No Thanks or Remind me later they get an error:

An error occurred. The iTunes store could not process your request.

Then the message won’t go away.

Here are some steps to try for this issue:

1. Unplug the iPod Touch and disconnect the computer from the Internet.

2. Close iTunes.

3. Wait a few seconds and Re-Connect the iPod Touch.

4. Start iTunes.

5. When prompted with the message, click Remind me later or No Thanks, then OK then quickly click the X button at the top to stop loading iTunes shop.

6. Close iTunes and reconnect to the Internet.

7. Start iTunes.

By default, iTunes has an option when you right click on a song to Convert Selection to AAC. This format isn’t friendly with some music players. What if you want to convert the music to MP3 format? Well here’s how to enable the Convert Selection to MP3 option in iTunes.

1. In iTunes, click on the Edit > Preferences.

2. Click the Advanced tab.

3. Click the Importing tab.

4. On the Import Using menu, select MP3 Encoder click OK.

Now the option to Convert Selection to MP3 will be available when you right click on an music track.

Need to extract the music files off of your iPod to your PC? I located a handy tool that will take all of the music files from your iPod and convert them into MP3 format. It will also copy your video files as well.

The tool is called iPodExtract. I prefer it because it has a very simple interface. Just select your iPod drive, then select where you want the files to go. Please note that the iPod must be enabled as a hard drive before using this tool.

How to share your iTunes music list to other users on your network.

1. In iTunes click Edit > Preferences.

2. Click the Sharing tab.

3. Check the box to Share my library on my local network. You can also restrict music sharing to selected playlists or password protect your music by checking Require password: and typing in a password.

If you’re doing this at your office, you may want to reconsider. Music sharing can be very “chatty” over the network, and system administrators hate it. As for me, it’s worth the risk to allow my co-workers to listen to my Micheal Bolton tunes.

How to make iTunes your default player for mp3, wav or almost any type of audio files.

2. Click the Advanced tab.

3. Click the General tab that is located in the Advanced section.

There have been a few times when Winamp has been the default player, and this box was checked anyway. I would have to uncheck the box and then recheck it and click OK to make this change.

With this setting enabled, iTunes should play all audio files it supports from now on.

Dear Apple,

I was using iTunes today and found a song by Enrique Iglesias. Oh how I wanted to hear his lyrical mastery in the song Don’t Turn Out the Lights. However when I double-clicked the song, the classic exclamation mark appeared to tell me the song has somehow disappeared. My heart was so broken. I was so ready to lip sync to the song in my whitey tighties.

To prevent this from happening again, I have searched high and low for a solution to rid myself of songs that do not exist on my hard drive anymore, but still appear on my iTunes library list. This doesn’t appear to be a feature of your software at all.

When you find the time, do you think you can add a Rebuild Music Index feature or an option to remove songs that don’t exist into your software or something? Otherwise I will be forever cursed with having over 500 songs listed in iTunes that don’t exist because there is no way to sort them and delete them all at once.

Sincerely,

Mitch

P.S. I chose to provide you a photo of my screen instead of me in my whitey tighties as I had intended. Let me know if you would like to see that instead.
