How do you sync iPod Touch music library to iTunes Match for transferring to/using on main computer iTunes?

Question

Hello, and thank you for any help anyone can offer. I subscribed to iTunes Match to transfer my music that's been stuck on my iPod Touch (iOS 5.1.1) to my new computer.
First, some background to explain my problem. On an old laptop, I had 15,000+ songs (mostly video game music downloaded online) that I synced to my iPod Touch. The computer containing that music started having trouble and likely died. I was unable to afford having it looked at, but all the music from it has remained on my iPod Touch.
Recently, instead of trying to have the old computer fixed, I bought a new laptop. I was looking for a solution to get the music from my iPod Touch onto my new computer, since I know syncing with it would cost me every song I have on the iPod Touch that I didn't download on iTunes Store. I thought iTunes Match was the solution, that it would bring the music on my iPod Touch to the iCloud, and I'd at last be able to download my huge library onto the new computer from there.
Now, the problem: I had to purchase the iTunes Match service on my laptop iTunes. It put all my purchased music from the laptop on iTunes Match. Well, when I go to iPod Touch and try to turn on iTunes Match, it says: "iTunes Match will replace the music library on this device." I assume if I do that, it'll wipe out my 15,000+ iPod Touch songs from my old laptop and replace them with the 1200 or so that I've purchased from the iTunes Store (which I already have on my iPod)!!! That is the last thing I want to do! Is there a way of getting my iPod Touch library to the cloud so I can access it on iTunes, or have I wasted $25 on iTunes Match? If I wanted to replace the 15,000 songs on my iPod with the little library of purchased music on my new computer, I would just plug my iPod into it and sync! Furthermore, my purchases were already available on the iCloud when I authorized this new computer, without spending a dime. I've put a lot of time into my library, and making playlists as well. Any help getting my iPod music on iTunes Match is greatly appreciated! Sorry if I've overlooked something obvious, this is my first experience with cloud-based services.

iTunes Match does not work this way. The service does not scan the music on an iOS device, only an iTunes library. For your music to be available in the cloud it must first be in an iTunes library. See the following articles:

An iOS device or iPod is not a storage device or backup of your music library. It is your responsibliity to maintain a backup of your music and other personal data.
