Songs not uploading to the cloud on iTunes

Hi, this is really really irritating. I bought some songs from Traxsource.com like I regularly do, then drag them into iTunes so that I can play them on my way to work on my phone. But all the tracks are still showing 'waiting' and will not upload to the cloud. Everything is updated etc etc etc so this is really annoying as I pay for iTunes Match.

Why Apple staff does this happen? I want to listen to the music that I purchased.

When I check online no body seems to get an answer that works.

Thanks
