How do we deal with bad players in music when every listen translates to payment?

For a few weeks in a row now, Chris Brown has appeared in my Spotify Release Radar. I’m not sure why, because I don’t follow him, nor do I really listen to similar music, but that’s a different topic.

The issue I have is: I do not want my streams to put money into the pockets of abusers (Chris Brown has a history of violence towards women, and victim-blaming). So that means I can’t really listen to my Release Radar in the background, or most curated playlists for that matter, because I want to make sure Spotify never plays those tracks to me.

I’m singling out Spotify here, because I’m an avid user: basically all streaming services have this problem. I’ve made the case for a global ban button for particular artists before, when I wrote about the Moby problem on Spotify. Basically, in curated environments, it would be nice to give some control back to the user and let them blacklist certain artists they’re not comfortable with.

Not only would this give listeners a more manageable overall experience, but it would also allow people to immediately make sure their money doesn’t go to abusers (and in the aftermath of the Weinstein fallout, surely Hollywood’s revelations will start spreading to the music business too).

But there’s another issue: in the streaming era, how do we listen to controversial artists without sending money their way?

For example, some brutal details around rapper XXXTentacion came out a while ago. He comes across as an abusive monster, and regularly gets into fights with fans. Yet, he’s still very popular. I’m curious why – is the music that good? I opened Spotify to check him out, but stopped myself from hitting the playback button, being aware that listening means money will go towards him (or his label, and seriously, they should do a Netflix and drop this dude + donate profits to causes that help victims / survivors of abuse).

But the ‘Chris Brown problem’ is that dudes like this keep being put into popular playlists, keep appearing in users’ personal playlists through algorithm recommendations. As listeners, we need a way to shield ourselves, and prevent our money from going into the pockets of these people.

If Spotify and other services are serious about their passive ‘lean back’ experience: give us a blacklist button. Let us ban Chris Brown.

Meanwhile one Reddit user has a suggestion for when artists you like collaborate with such people (which I’m sure a lot of readers won’t like):

Almost every week, Spotify adds a Moby track to my Discover Weekly or Release Radar playlists – probably the playlists I listen to the most. The problem is: I don’t like Moby, and he’s not going away.

I’ve figured out exactly why Spotify keeps recommending me Moby. I’ve also figured out what types of user behaviour can discourage a recommendation system from continuing to recommend certain music. On Spotify, skips are weighted heavily. That is to say, if you skip a track, Spotify interprets it as you not liking a song or artist. I quite consistently skip the Moby tracks in my recommended playlists, but a week goes by and there he is again.

The Moby problem is not actually about Moby. It’s about the way recommendation algorithms work, and about the way we feed music data to them. The reason why Spotify keeps recommending me Moby is because I have a few Moby works in some of my playlists. I actually like his early rave stuff from the 90s, but I don’t care much for his chill out and trip hoppy stuff. Moby is perhaps also one of the most remixed electronic artists. Occasionally (and rarely), a really great remix sneaks into my playlists.

Hypothesis: playlists are weighted more heavily than skips

Three factors around playlists seem to be playing a role in Spotify’s assumption that I love Moby:

Moby’s inclusion in my playlists (passive)
Moby being played from my own playlist (active)
Moby being added to my playlists (active)

The weight in the algorithm should probably get heavier towards the bottom of this list, since it signals stronger intention and commitment. There may be many other factors at play too.

The fact that I like a couple of songs from an artist, some of which from over 20 years ago, does not mean I’d like to be kept up to date on his newest music though. Most of the Moby tracks that appear in my Release Radar are actually inter-genre remixes, so that really doesn’t make much sense either (e.g. if I like drum & bass, why would I like a techno remix of a drum & bass song?).

The remix problem

Then there’s another issue with remixes. One of my most-played playlists, called If Red Bull was Music, includes an EDM remix of a Moby track. It’s the only Moby track I listen to regularly, besides perhaps the Moby stuff in my Discover Weekly and Release Radar, when I forget to skip.

The problem is: it’s not a Moby track anymore. Sure, Moby is the original artist, but it doesn’t sound like a Moby track at all. It’s almost like categorizing a hiphop beat that samples Mozart as a piece of classical music.

It seems like Spotify is barely taking this into account when two artists can be lumped into the same category (electronic), even when that category is too broad to mean anything.

The solution

Let me banish artists! Give me a big fat ban button.

But hey, I’m a product person: I know the Moby problem is a symptom and you shouldn’t develop features to address symptoms — that’s how you kill a good product.

Spotify has a great product and Discover Weekly & Release Radar are a strong part of my music habits nowadays. So what it needs to do, is get better at understanding users’ actions and intentions, and how they weight them.

Personally, I think it’s important for them to look at how users interact with the music in their recommended mix playlists, and then weigh that much heavier. No engagement with a certain artist (or actually: skips), then that artist slowly becomes invisible, like in the Facebook news feed.

So to whomever is succeeding Matt Ogle, one of the creators of Discover Weekly, who just departed Spotify for Instagram, please solve my Moby problem. Let me escape this filter bubble.

(Just in case: hey Moby, I love your music, but most of it just doesn’t fit my taste so well. Keep doing what you’re doing!)
