Song Requests are one of the main ways fans can support the artists they love. When artists are live streaming and if they have one set up, a Song Request list will be displayed on the side menu, showcasing all the different songs that the artist has in their repertoire. A fan can pick a song and donate Love to bump up that song to the top of the list, making it more likely for the artist to sing it.
The Song Request list can be accessed by clicking the "SONGS" header on the menu to the right of any stream you're watching. There's a search bar you can use to filter the songs to quickly find the songs you're looking for.
