Wrong album and track lengths

I wonder why so many albums and tracks are listed with wrong timings.

Check the following album, for example.  It is listed as having 7+ hours of music, but it is a 3cd release, with only 2h20m of music.  Individually, the songs themselves also have wrong timings listed. 

There are so many others that have this same problem.  I see those timings on PC and on Android.
