DoubleTwist
I found these guys. They seem to be pretty serious developer and CNET gave it 4/5 stars, so I would trust it not to be malicious.

Basically, you may have some issues, and it may require a bit of fiddling, but if it works it's worth it.
You install their free PC program and use it to sync with music players/phones.
But the from what I've seen, DoubleTwist doesn't recognise the GS3, yet.

Hello,
The Galaxy S3 only has USB MTP mode, which doubleTwist was not designed for as it expects USB Mass Storage (MSC) mode.
We are currently working on adding USB MTP support to doubleTwist.
In the meantime, you can use AirSync to sync with USB MTP only devices such as the Galaxy S3 and Android 3/4 tablets.
Here's a quickstart guide to AirSync.

Thanks,

Given what they said, unless you are willing to wait for support to come (i doubt there is an ETA on this) you can shell out 5 bucks (AUD, so more like 3 GBP) and install AirSync on your Droid.
You will still need to install DoubleTwist on your PC.
Also regarding iDump i mentioned, it may not be applicable...

Description of iDump
This program will allow you transfer your songs from your iPod to a PC, iDump does come wrapped in installer but you can simply drop the .exe in the root directory on your iPod and run it from there.
Connect your iPod and run iDump and you'll have access to all your songs, select the songs you want to transfer then pick a destination directory and how you would like your songs to be named. And then sit back and transfer all the selected songs to the PC.
Note: Currently not compatible with iPhone or iTouch. This link takes you to the vendor's site, where you can download the latest version of the software.

If you have an ipod touch or iphone but not an ipod, then it seems this wont work. However if you have an ipod, you can have your music synced to it, and run idump from your ipod. But as i mentioned previously, not sure how meta-data would turn out. Also, that free version is 4 years old and many download links seem broken.
Here is a
link (CHIP), and another
PHP-Nuke. Note i cannot guarantee the security of these downloads.
You can try it you want. I probably would. Most downloads are 1.1MB, so I'd be suspicious of anything other than that.
I wouldve tried having a better search but my internet it slow at the moment.
