Google parent company Alphabet has released its Youtube Music app on both iOS and Android devices.

The YouTube Music app attempts to differentiate itself from rival services, such as Spotify, Apple Music, Pandora and other similar services, by focusing on music videos as well as covers to popular songs. The app displays video stills of the song you’re currently listening to, although expect some audio-only tracks to be thrown in there as YouTube Music features a catalog of nearly 50 million songs.

While the promise of 50 million songs sounds promising, nearly 20 million of those are fan covers and independent artists.

YouTube Music curates its most culturally relevant songs and music videos of the moment in a single playlist called the Daily 40. “We want the Daily 40 to be the place you go to know what everyone else is watching and talking about and sharing,” said T. Jay Fowler, the head of music products at YouTube. “If a song is blowing up on YouTube, this is where you’d find out about it.”

YouTube Music is free through ad-support, although if you have a YouTube Red subscription, you’ll be able to listen ad-free.
