Spotify - Removing artist from playlist

I've searched the Spotify forum boards and internet widely to no avail. I cannot figure out a way to remove an entire artist from a playlist i've created without downloading the full desktop version of Spotify, which i can't do on my work computer due to administrative rights.

This is a topic i've seen posted several times on their boards but nobody ever gets an answer. Seems like a pretty basic function which is why i figure i'm just missing it somehow.

Can anyone help me figure this out? I'm using either the android app or browser version of spotify.
