In the last few years, basically every platform of consequence has made its own take on TikTok's signature scrolling feed of vertical videos. YouTube Music is the latest. Today, the app will get a vertical video feed called Samples that YouTube describes as a one-tap way to quickly sample and find new music. 

Samples lives in a new tab at the bottom of the app, alongside the home feed, your library and the explore section. Tapping Samples automatically starts a short vertical video clip of a song that YouTube Music thinks you'll like. Naturally, it's pulling songs based on your taste profile, with an emphasis on artists that you like, and related ones who you might not have heard before.
