Album name & Song name/no the same... music totally different

Ok her is what happened... Bought a new iPhone 6s Plus... Very happy.. BUT

During studying I like to listen to "Feng Shui - Ancient Eastern Spirits", an album that I bought in the ITunes store a year or 2 ago.

So Started my new phone that loaded the album from iTunes and... wait... that's not right... this doesn't sound like the right music..

So I looked around and it appears that the album name is okay the song names and position on the album is okay BUT the music has been changed.

What the h..? Hmmm I have an iPod which has the album too and yes different... all song durations are different. Eg the last number on the album called "Ocean" has a playback time of 14:49 while the same song on iTunes a playback of 8:12 and yes.... the music is quiet different.

Checking on the internet reveals;

The website; http://www.last.fm/music/Ancient+Eastern+Spirits/Feng+Shui as http://www.emusic.com/album/ancient-eastern-spirits/feng-shui/11266716/ have my (correct) iPod version, the version I originally bought in iTunes... Then I discovered also sites with the same (wrong) version as iTunes.....

MAGIC.... somebody a clue?
