Eurovision Song Contest KARAOKE VERSION

I just discovered on Deezer that there were official Karaoke Version albums of the Eurovision Song Contest. However, if 2018 is fully available on Deezer, the last years are either not listed at all, or ost of the songs are greyed out and can’t be played.
And even though everything was there, I often download karaoke MP3 to train my singing for little local contests happenning in my town, and of course I need the backing track for the contest, which is impossible to do with Deezer, as I have to give them a MP3.

So, I wonder if anyone has the official Karaoke Version albums of every Eurovision Song Contest for the last 10 years (if they all exist of course, as it seems that, according to Discogs, 2011 was the first Karaoke album), most importantly since 2014, but before would be great also.

Thanks a lot in advance!!
