built a web app that uses k-means clustering on artist genres (one or multiple) to automatically organize Spotify liked songs into playlists. clean UI.

you might have to click refresh playlists couple of times to get what you want. comments are appreciated. thanks!

You got a back trap. When I try to navigate back from the playlist screen it goes to the processing screen, and then repeats the processing request every time I navigate back after that. Maybe a bit gnarly if that is kicking off the spotify fetch each time.

Aside from that, nice, I'm listening to one of the playlists right now.

thank you for the feedback! glad that you're enjoying!

Congrats on the launch!

Interestingly I've been working on an almost exactly the same kind of thing and was hoping to release it soon. I've applied to get my app's limits lifted on Spotify, but haven't heard back from them yet...How long did it take for you?

dogancan

It took 19 days

vulkoingim

Ah nice. I read that for some it was taking months and I was losing hope

Not working from my side: Get error in console

``` index-DpuJbHxC.js:40 TypeError: Cannot read properties of undefined (reading '0') ```

Love the idea, although I feel like the playlists generated aren't... great. For me it was grouping things in a pretty odd way that didn't make sense (e.g. Bob Marley under a "punk" playlist)

Last time I checked Spotify's genre categorisation system was really weird so that doesn't surprise me.

dogancan

yeah, exactly. Artists genres are weird and the algorithm uses a weighted system to determine the clusters. But you need to try a couple of different options to get what you want.

I love the design. Very minimalistic. I was wondering is there any plan to integrate apple music support?

dogancan

on the way!

Love the idea and design but it doesn't seem to be working atm. Logged in via Spotify and it starts to do the import but then kicks me to the playlist gen almost instantly. Can move the sliders but button click is dead.

Console is showing a 502 error from Spotify API so may be a snag there (https://api.spotify.com/v1/me/tracks?limit=1 502 (Bad Gateway)).

dogancan

sorry to hear that. i confirmed that it is working now. can you try again?

rglover

Just tried again and getting same result. Shows the progress bar on import for maybe 2-3s and then kicks to the sliders UI. Console is showing "Error: Failed to fetch track count" now.

I also de-authed the app on Spotify and tried from scratch. May be a rate limit issue or some missing scope needed on the OAuth permissions.

If you need help debugging, hit me up: me@ryanglover.net.

dogancan

will do! thank you.

Keen to try this but I don't have any "Generate" button and it says I have 0 songs/artists in my library.

dsp_person

this would be cool for soundcloud likes

weirdly I only listen to spotify if someone sends me something

dogancan

Added to the list. Thanks!

camcaine

Cool. Would be great to see the source

quinnjh

Seconding - cool but curious about how it works

I agree, would be useful if adapted to nicer systems for access to music.
