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!

Cool. Would be great to see the source

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

Seconding - cool but curious about how it works

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.

i don't think it's your fault. spotify's entire website is down for me right now, i'm getting "upstream request timeout" and "upstream connect error or disconnect/reset before headers. reset reason: overflow" just trying to load the homepage. this happens every couple of months.

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!

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

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

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.
dr_kiszonka
MusicBrainz and LastFM have much better genre information and on a track level, IIRC. Their APIs are free, I think. You could use them to look up genres.
dogancan
yes will integrate more genres in the feature. especially apple music even have song genres, whereas spotify only has artist genres.

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
dsp_person
this would be cool for soundcloud likes

weirdly I only listen to spotify if someone sends me something

Not working from my side: Get error in console

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

It is amazing. I loved it. Would you consider to do samething with other apps.
