I often listen to the playlists suggested under the "browse" function. All to often this freaking "what do you mean" by this little freakingly annoying Justin Bieber comes. Everytime I have to go and skip it. I would love a blacklist on spotify where I just state Justin Bieber and then, everytime there is a playlist and a bieber song comes, it just skips to the next one. Naturally everyone can choose who to add on their blacklist so everyone can avoid their biebers.
