How do I transfer my music library between computers?

My music is a mix of iTunes downloads, CDs I own, and CDs I have borrowed and no longer own (physical CD). Every time I have transfered my library between computers, I seem to loose music. I don't want to back up ALL my music onto CD (does anyone actually do that/have time?) and (possibly as a result) I get tons of the little exclamation marks next to the track titles. These tracks cannot be found, cant be recognized, or aren't authorized to be played, etc. How do I avoid this problem? Do I have to make CD copies for hundreds of songs?! Thanks for the help.

ITunes is just a program that plays music files on the computer and puts it into one interface (aka ITunes) where you can access it. If you move the actual files on your computer, ITunes will not know what happened to the files. I would suggest copying all your music to the new PC if you want to access it from there, do not move it. The exclamation mark you are getting means that ITunes the program cannot find where the music is located because it has been moved.

You can share your music from your old PC so that your new PC can access it (home network). That PC must be on in order for your new PC to access it though. Your probably better off moving/copying the music to your new computer. Copying your music to the new computer provides a backup of your music on your old PC incase you have a hard drive failure. Any new music you add will not be there though.
If you have a network, you may want to put the files in a shared folder on the network and then put them back on ITunes on your other computer.

If that doesn't work, you may want to try to use a flash drive to see if you can transfer them that way.

Good luck and I hope I helped you!
Buy or borrow a USB key (size depends on size of your library), and then transfer it.
