We recently got to attend the Junction hackathon in Helsinki, where over 1,000 awesome developers showed up to build awesome hacks. We got to help 30 teams build some pretty incredible projects, and were delighted to have had the most popular challenge category at the whole event!

Here are some photos and a few of our favourite hacks.

We were delighted to meet so many of you, from brand new coders to seasoned veterans. In the end, we saw over 30 teams build hacks that use the Spotify Platform. We wanted to find inspiration to share, so our challenge was to find the Most Creative Use of the Spotify Platform.

Out of all of the projects, here’s a few of our favourites:



Spotter, our winning hack, is a platform for smaller artists and playlist curators to connect with each other. The basis of this hack was that smaller artists find it difficult to get noticed by listeners, and by getting featured on smaller playlists, they can have grow their own reach.

How they used the Spotify Platform:
Used the Audio Features API to recommend playlists that an artist can apply to be curated on.

Why we selected it as a winner:
Spotter was an original hack, that addressed different audience to what we usually see - artists instead of listeners - and was executed brilliantly.

Tuneout is a hardware controller for Spotify, built using a Python script that communicates with the Spotify Web API.

Why it was one of our favourites:
Tuneout is an playful, high-quality hardware hack, representing the learning spirit we love about hackathons - it was developed by first-time hardware developers!

Spotify Crowd

This hack was a fully implemented crowd music app. This hack was really well designed (it felt like Spotify) and worked very well. Spotify Crowd consists of a central web app along with an accompanying mobile app that works in both iOS and Android.

Why it was one of our favourites:
Spotify Crowd uses our Web API & Web Playback SDK to power the interface, and built their own solutions to tackle a few problems:

  • First, the team used an external API to identify the genre of a track, and displayed the most popular genres to the host.
  • Second, they built their own queueing system. Spotify Crowd tracked when a song would end and would automatically fire a command to play the next song.
  • Thirdly, Spotify Crowd used our Audio Features API to control the kind of music to get queued, which enabled the host to filter the queue to their particular needs - an awesome, innovative use of the Spotify Web API!

Sadly they don’t have a demo up, but you’ll have to trust us - it was a really great hack!

The Spotify Crowd application


The hack is similar to Spotify Crowd, but instead of allowing people to request songs, partygoers each select a playlist which Partify will merge into a shared listening queue. It has a simple mood filter allowing the party host to fade between “lounge” and “party”.

Why we liked it:
Partify uses the Web API, especially the Audio Analysis API and Connect API to build a great collaborative listening experience. It has a nice polished interface, and is an interesting implementation of the oh-so-popular social listening concept we see often at hackathons.

Final Notes

We love supporting you in building your hacks. If you have not already, check out Spotify for Developers and our brand new Web Playback SDK. As always, reach out to us if you’re working on something cool with the Spotify Platform, we would love to hear about it!

We hope to see you at an event soon!

Happy hacking!
