Been using projectM Music Visualizer TV for a couple months now. It’s basically an app that takes the music playing on your Android TV and turns it into these really cool psychedelic visuals. Pretty solid if you’re into that kind of thing.
Here’s what you do: you just start up the app and it’ll sync to whatever music you’ve got playing – whether it’s Spotify, Pandora, or just the default media player. There’s also a built-in music player so you can control the tracks from within the app. And the visualizer effects are super customizable, with over 200 different presets to choose from.
Look, if you’re into music visualization and want something that works well on your Android TV, you’ll probably like this. It’s not perfect – the interface can be a bit clunky at times – but overall it does the job. Worth checking out if that’s your kind of thing.
