SO I had to force quit iTunes when uploading my music.
Now when I restarted iTunes, I had to sign in again and turns iTunes Match back on.
It started going through the whole process of matching my songs and now it says
"iTunes Match is matching a library from another computer."
"Only one computer can be matched at a time. If you continue, the other iTunes Match session will be stopped and this computer's library will be matched instead."
WTH?
