Hey Guys.

I have a couple of really dumb questions..

Firstly, why does the Spotify logo on the Telsa center console have an umlaut over the O?
I haven't seen it on any other Spotify artwork anywhere...

Okay, real question now.
Under Spotify / Your Library / Stations it makes stations for the music I listen to.
I like this, at it seems to create a radio station with my songs. I'm happy.

My teenage son was in the car, and played a bunch of his songs.
Now my Stations channel is filled up with his "music" most of which contain words I cannot type here or I'll get banned.

Is there any way to clean up this "stations" section.

I cannot do it from the Spotify app.
I cannot do it from Spotify Station app.
I cannot do it from the web interface.

Any suggestions?

Nick.
