I am in Brazil and I run Spotify Free on Windows 10 and on Android 5.1.1 for Asus ZenFone.
My issue is that I have discovered that the Song "Because I Love", by Majority One in the Album Rainbow Rockin' Chair actually plays a wrong audio file. One has only to make a quick YouTube search for the song and compare them to realize that it is not the right one.
This happens both on Desktop and on the Smartphone.
It would not be a big problem if this was not the only instance of this song in the entire platform.
