Q: Songs cut off in middle downloaded latest American idol ablum

That is usually the result of a downloading problem.  You can download fresh copies (at no charge) by following this guide:  iTunes 10 for Windows: Download previous purchases from the iTunes Store

In the unlikely event that the new copy has the same problem, it could be a defect in the store master file.  If that happens, you cannot correct it yourself, so report it to iTunes Customer Service.
