Mono is a music discovery and playback app that brings together multiple sources to provide a seamless music experience. With Mono, you have access to a vast library of artists, their releases, top tracks, and media. The app allows you to configure and prioritize music sources for playback, including your local files, Soundcloud, Subsonic, and YouTube, both on your device and on Chromecast.

In addition to music playback, Mono offers various features to enhance your music discovery journey. You can explore artist bios, view images, and check out upcoming concerts. The app also suggests similar artists and allows you to build, save, and share playlists effortlessly. Moreover, Mono provides several ways to automatically generate playlists based on top tracks overall, genre, country, tag, as well as Last.fm, SoundCloud, Spotify, and Billboard charts.

Mono respects your privacy and only requests necessary permissions. The app does not access your contacts, but it does require permission to read your registered emails on your device for account purposes. It may also request access to your calendar to post concerts, microphone for text-to-speech functionality, and location to display concerts in your vicinity.
