Dragging and Dropping in ITunes Music

Steve,

OK, if right-click > open with... does not work, it is unlikely the other methods will succeed.

A few questions:

1. You said the files were MPEG-4. Is it possible that they are .mp4, i.e. protected files?
2. If you take a "known good" MP3 or AAC file that was not even on the old machine, can you play it on the new machine using Right-click > Open With?

Hi, the files are .mp4

On the new machine, do they play in QuickTime?

Hi Stevie,

That codec could apply to either a protected or unprotected file. Look at the file extension. Is the file extension .m4a or .m4p? ( BTW, .m4p is what I meant to write earlier, not .mp4.)

Also, just in case something happened to the files in the copy process coming from the old machine, can you try a brand new "known good" AAC or MP3 on the new machine?

Well that is good news.

It would be valuable to know if a brand new MP4 would plan on the new machine. That would help distinguish if you are seeing a problem that occurred in the copying, or if something is wrong with the new system. Up to you if you want to give it a try.

• Right-click the MP3 and choose Open With > iTunes (or Music)

...

Stevie, "Right-click the MP3 and choose Open With > iTunes (or Music)" is pretty much the acid test. If you do it on a valid audio file, that will start it playing whether it is or isn't already in the library. (Of course, it only works one file at a time.) If you have a bunch of files that fail the test, try re-copying them from the machine where they work.

Good. At least iTunes is working. :-) Take a random sample of the files from the old machine and copy them to the new machine by any means different than the way you did it the first time. Do they work on the new machine?
