How do I reverse sync from 4s to MacBook Pro?

Question

So I got nearly 200 songs, not much.
So I wanna sync them from my phone, which is a 4S, to my brand new MacBook Pro (I got it last night xD).
Problem is, about 160 of them are not iTunes purchased, they were downloaded from YouTube to my desktop, and well yea. I tried Sepuni or something like that, but it wouldn't transfer everything in playlist forms. I am very OCDish on my music. I keep it very organized, and I wanna keep it that way, and it took me about and hour and half to rename all the files and move them into folders in my Music folders, and double the time for iTunes. *sigh*
So basically, how do I get all my music onto my Mac the way it's organized on my phone without paying for anything?

Answer 1

Easy. You copy the whole iTunes folder from the computer with which you previously synced to the new computer, replacing the empty iTunes folder there, then start iTunes.  Otherwise you may well be out of luck, and that goes double if you expect these utilities to be free on the Mac platform.  Oh, you can export the playlists from the iOS device, but that's just the text listing, not a complete package of playlist and media.

Your i-device was not designed for unique storage of your media. It is not a backup device and media transfer was planned with you maintaining a master copy of your media on a computer which is itself properly backed up against loss. Syncing is one way, computer to device, updating the device content to the content on the computer, not updating or restoring content on a computer. The exception is iTunes Store purchases which can be transferred to a computer.

For transferring other items from an i-device to a computer you will have to use third party commercial software. Examples (check the web for others; this is not an exhaustive listing, nor do I have any idea if they are any good):
