I omiited the following earlier, but there is most unfortunately the possibility that the 'corrupted' files you have attempted to download are deliberately corrupted.

Deliberately corrupted and then shared by organisations who are in one quise or another affiliated with the music recording industry.

There are numerous threads and posts on this subject here in the forums.

As an aside, for those who are doubtful of the ability of individuals or groups do this, just think how many files are covered by people attempting to install their 'dialer' applications on your machines... And, these 'dailer' people are very small-time in comparison to the music recording industry.

This may seem strange to say, but hopefully it is a problem with either your systems or your software.
Those types of 'problems' can be fixed !
