[X4U] iTunes information extractor

[Craig A. Finseth]

I'm trying to split up my iTunes library between the ones that I
purchased and the ones that my son purchased.

I'm looking for information that can be run in bulk over my library
(~15,000 songs).  I'd like it to report on some combination of:

- did I rip it myself, or was it purchased from iTunes?

- if the latter, who purchased it (presumably email address in the
  metadata)?

- as a bonus, it would be nice if it could report on the bitrate
  and/or iTunes Plus status.

Output should be lists of (full path) filenames (so that I can hand it
off to shell scripts to do the heavy file and volume stuff).

If anyone has or knows of an application that can do something like
this, or information about how to parse the .m4p files, I'd appreciate
a pointer.

Speed is not critical: this is a one-shot item.

I'm willing to pay for the app/library.

Thanks,

Craig
