Assuming you are in a region where you are allowed to redownload your past music purchases, delete the broken tracks only from your iTunes library, go to the iTunes Store home page, click the Purchased link from the Quick Links section in the right-hand column, then select Music and Not on this computer. You should find download links for your tracks there.
If you don't see them straight away it may help to restart iTunes. While downloading select Downloads in the left-hand column and make sure Allow Simultaneous Downloads is unticked.
If the problem persists, or that facility is not yet available in your region, contact the iTunes Store support staff through the report a problem links in your account history, or via Contact Support.

I'm in north America region so can I do this? Also what do you mean delete only from iTunes library, or delete whole file to recycle bin? If just delete from iTunes how do you do that? Also is there a way to redownload whole cd and not each song individually?

Yes, you can download your past purchases in the US.
I meant delete the tracks you know are broken, some people are deleting and redownloading entire albums but it would be a shame to throw away a good track only to get bad copy and have to do it again.
Delete from the main music section of the iTunes interface and let iTunes send the file to the recycle bin. If you delete from the purchased playlist, or delete the physical file from Windows Explorer, iTunes thinks you still have the song so won't offer it for download.
Yes, you can redownload all the tracks of an album at once, but it may be best not to as stated above.

Your best bet is to delete all of the songs that won't play through. The next step is to go to the Purchases tab in your iTunes and in the bottom right hand corner it will say "Download Previous Purchases". Go to the "Not on this Computer" tab, find all of the files you deleted, and re-download them. That should solve your problem (:
