Why does Spotify add a whole bunch of unwanted songs to my queue?

[stuyvenstein]

I'd like to know why Spotify puts unwanted songs onto my queue, when I requested for a single album to be added? Or better yet, how do I prevent it from happening?
Let me explain:
So I browse to any artist's page, then hit the play button on any album
(As can be seen here: https://postimg.org/image/opbsuz6n9/ ), 
Then, instead of adding just that albums contents, as can be seen here: https://postimg.org/image/44nl5eu6t/
It ends up adding a whole bunch of unwanted music, as can be seen here (at the bottom):

Now, I've repeated this process with 'Repeat' and 'Shuffle' enabled, and disabled. - No noticable difference.

My setting to 'continue playing other music when the queue ends' is also disabled, enabling it drives me even more insane.

I dislike the recording quality of most live music, and when I tell spotify to play a specific album, then surely you can understand my frustration when a live song starts playing but I didn't put it there.

My issue is not just the fact that it adds live music, but when I want to listen to an album, I want to listen to an album, not 50 different albums that include live music. Please spotify, please fix this.

I've put together specific playlists with plenty of songs. Spotify now adds, apparently randomly, to these playlists when I try to play them, and generally adds songs that I actively dislike.

If I can't listen to the songs I want to listen to, I'm not sure why I'm listening to Spotify ads; I could buy all of the relevant songs for the price of a couple of months' Spotify premium membership.
