Many of my songs are incomplete and will cut out towards the end

Question

I've had this problem for several years now. I have over 4,000 songs (most of which were purchased through iTunes and the rest imported from CDs). A lot my songs will play for a little while and cut out at the end. Sometimes it's just silence but lately the next song will just start playing. When I go into my iPhone to check it out it still has the album artwork and everything from the previous song.
I've contacted support several times about this over the years. The first time I was told to connect to my computer and reload all my songs. This seemed to fix many of the songs but then I would notice other songs had the problem. I was then told to redownload all of my purchases and to sync again. Same thing happened. It seemed alright for a while until the same problem occured. The third time I tried to get it fixed I was advised to delete the song from my phone and redownload it through the iTunes app. This seemed to fix each individual song (though its not very practical). But now even that no longer works. I delete the song and redownload it only to find that it still skips to the next song without registering it. It's driving me nuts and, while I can't prove it, I'm pretty sure the problem is growing. I notice songs that played fine a few weeks ago do the same thing. Considering the amount of money I've spent purchasing music it's maddening not being able to listen to a complete song.
Is there any fix for this? I've found similar posts but no new advice. Any help that anyone can provide would be welcome.
Some additional info...this happened when I had my iPod touch, my iPhone 4 and now my iPhone 5. My software is up to date.
Thanks.

Assuming you are in a region where you are allowed to redownload your past music purchases, delete the broken tracks 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 the Downloads widget near the top-right (iTunes 11) or in the entry in the left-hand column (older iTunes) 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.
