LineupSupply’s app turns music festival posters into Spotify playlists

If you often find yourself creating Spotify playlists to prepare for an upcoming music festival or to relive a favorite past show, a new mobile app called LineupSupply can now make that process easier. This smart utility lets you upload a photo of a music festival poster to automatically turn it into a Spotify playlist in moments. Alternatively, you can use the app to find playlists created by others or, with a one-time purchase of $1.99, tap into music recommendations based on artists in images you’ve uploaded.

The new app was created by longtime Seattle-based iOS developer Brett Bauman, currently a senior iOS engineer at Loom.

Bauman says he came up with the idea after researching a Spotify playlist of the lineup at an upcoming music festival, Portola, which he plans to attend.

“It made me think people were making them manually and I couldn’t find another service that automates,” he says.

The developer started working on the app over the summer and released the current version at the end of August. Much of that time was spent waiting for Spotify to come up with an API key that allowed the app to work, Bauman notes.

On first launch, you will need to authenticate with your Spotify credentials before starting. You can then upload a music festival poster image to the app to start creating your first playlist. The app currently supports images with text in English, French, Italian, German, Spanish, Portuguese or Chinese, and all image scans are done locally on your own device.

In addition to Spotify’s API, LineupSupply uses Apple’s Vision Framework to extract text from the music poster image, which is then combined with artist names and transformed into a music playlist. And while the app requires users to have a Spotify account, you won’t need to be a Spotify Premium subscriber to enjoy its features.

Playlists created by the app can last for hours, depending on the size of the artist list for the event in question.

Unfortunately, we found that the app struggled with atypical fonts and wasn’t always able to identify all the artists on some posters. For example, when we tested the app with an image for this upcoming Hopscotch Music Festival with colorful, bubbly artist names in various sizes, the app was only able to recognize a small handful of artists on the app. ‘attach. This could provide a start for creating a custom playlist, but we still had to fill in the rest of the playlist manually, as before. (Bauman says he is working on this issue.)

But other events that use more standard fonts, like this image for EDC Orlando 2022, performed much better, we found.

LineupSupply also lets you customize the playlist before it’s created by removing artists you don’t want to include in your playlist. And if you don’t want to do the work of finding and uploading your own image, you might be able to find an existing playlist created by other users in the “Discover” section of the app.

There is no limit to the number of playlists you can create with the free version.

For a one-time $1.99 upgrade, you can access a few more features, including the ability to set a custom app icon or further customize the playlist by controlling the number of songs per artist, options song sorting and playlist description. .

Paid users can also access personalized music recommendations based on the artists found in your uploaded images.

Bauman says he has other ideas to continue developing the app, including plans to support other platforms, like Apple Music. He’s also thinking about other ways to automate playlist creation.

“I’m really interested in exploring other mediums besides images for creating playlists, like videos and text,” he told TechCrunch.

Users created 100 playlists with the app in the first two days of its release, and now, about a week later, that number has grown to around 250. Of course, this isn’t a proxy for the number of users, as some people can be. use the app to access playlists created by others, instead of uploading their own images.

The app is free to download from the App Store.
