Please help me to reorganize and move my iTunes library from TC to an external drive

Question

A while ago I made the mistake of moving my iTunes library off of my mid-2009 MacBook Pro (currently running Mavericks 10.9.3) to my Time Capsule because it was too large for the 160 GB internal drive and I didn’t realize that it wasn’t the best place for the library.
Now that I’m soon to have two 4 TB Seagate Backup Plus drives I’m looking to move both my rapidly growing Aperture library off my laptop and transfer my iTunes files from the TC to one of the two Seagates.  On this Seagate there is a second partition for my Time Machine backup.  When the second drive gets in (I live in Peru and have to wait for the second drive) I will use it to make an exact copy of the first Seagate as a backup.
For some reason the music files on the Time Capsule reside in three different places:
/users/username/Music/iTunes/iTunes Music/Music/Band name/Album name/05 track name.m4a
or
//localhost/Users/…(same as above)
or
/volumes/my name Time C/Music/Music/Band name/Album name/05 track name/.m4a
How it came to be this way I don’t know.  I’ve only recently gotten access to my MacBook after leaving it behind for two years of travel.  How do I clean this up so that all files are residing in the same directory location and where should that place be?  I want to keep my internal drive as empty as possible so files need to go on this new Seagate.  I’m waiting on a FireWire 800 adapter to speed up the process of transfer.  Is there a way to efficiently move 400+ GB of music files from the TC to the Seagate drive?  I don’t know why in the third location (/volumes…) there are two /Music folders, which seems unnecessary.  How can I eliminate this across all files?  Is this something I can do using Automator?  Any other suggestions?   Thanks for helping me with a newbie situation.

Answer 1

   Yes you can go to > Music > iTunes folder and copy the whole iTunes folder and drag the folder to your external and then on the new Mac click and highlight the iTunes folder and then in iTunes click on the button at the top (add folder to library) and you should see all your songs transfer from the external to the Mac and all songs start filling up in your iTunes library on the Mac.
  This is the easiest method all songs and other media such as songs, movies, apps will be transferred over however you may not be able to keep ratings & last played counts using this method.
  To keep all metadata including ratings & play count use the Apple method exclusively for this if you have to have your metadata, play counts and ratings saved.
  I used scenario one above because it one of the simplest methods and I was just satisfied enough just to transfer all media over.
