I have the majority of my music on my laptop, but backed up to an external hard drive too. My method of adding new music is using the "Copy files to iTunes Media Folder when adding to libary" and then I delete the downloaded songs from my download folder, leaving just the ones iTunes copied to the media folder. My problem is when my external was plugged in and I added new music to iTunes, it added it to my media folder on my external HDD. When that wasn't plugged in, it added it to the media folder on my laptop. So now I have my library in two places, the majority of which are the same, but a whole bunch of recent songs are only on one or the other. How can I consolidate the two? I just tried changing the media folder location, and then selected the "Would you like iTunes to move and rename the files in your new iTunes Media folder to match the Keep iTunes Media folder organized preference?" option when prompted, but that only succedded in moving the files on my laptop. The ones that were on my external stayed there. Anything ideas? TL;DR iTunes library split between two locations, internal and external HDD. How to consolidate?
