🤟 Skrrt - Music recommendations, done right.
jajoosam (904)

I'm so excited to finally share skrrt with all of you!

I spend several hours every week curating my music - I can't rely on spotify recommendations to give me what I want. I want to be able to tell something the music I like instead of it predicting what I might like, very ambiguously.

skrrt gives me the music I ask for.

    "name": "Study Music",
    "seed_tracks": ["A lot", "Middle Child"],
    "seed_artists": ["21 Savage", "J Cole"],
    "instrumental": true,
    "key": "minor",
    "danceability": { // 💃
        "min": 10
    "popularity": { // 👀
        "max": 80,
        "min": 30
    "speechiness": { // 🎤
        "max": 40
    "energy": { // 🔥
        "min": 50

skrrt will be able to parse this filter, and then play songs similar to a lot and Middle Child (provided in seed_tracks) - the filter will also take inspiration from the artists in seed_artists.

But that's just the basics.

  • Because I'm trying to focus while playing music from this filter, skrrt will only play instrumentals.
  • I also want to listen to darker, thugger music with this filter - and choosing Minor keys will make sure that happens.
  • I want to be able to discover some music I haven't heard before, but also not listen to music that's super new and unreviewed - setting a maximum popularity to 80 and a minimum to 30 takes care of this.
  • I don't want tracks where rappers go crazy and 100% lyrical - setting a maximum speechiness to 10 makes sure I get more of the mumble kind.
  • To prevent super fast tracks, I set a maximum tempo to 100 - but I still want to keep the energy up (loudness, dynamic range) - which is why I set it to a minimum of 50.

And there's more! You can have customize all of this with skrrt.

Want to make your own filter? - and let me know if I can help!

I can't wait to hear what y'all think! 👊💥

Update: there's a newer version out at - haven't updated the original repl :)


Very cool. Is the repl open source? I'm guessing it uses the spotify API to get stuff like danceability, speechiness, ect.? It would be cool to see the code.

@Skalwol yep, its open source now - and yep, it uses the spotify API for most things (some custom implemented).

Code is super messy, but I'm happy to answer any questions :)
