I get an error for every single song download?

I use itunes match for my iPhone and computer so that I can listen to my music whenever, however when I try to download a large amount of songs it gives me an error saying the song can't download. I've done this before and it worked fine, but recently I added a bunch of songs to my library and it won't work not. Also, I tried updating my iPod today to 6.0 and it gave me the same error that it was giving me for the song downloads and stopped downloading when it got to 700 out of 800mb
