So I am a youtuber/streamer and when I stream I like to play music in the background. However, sometimes I like to use my stream highlights as recordings and don't want my stream music in my video. I figured that I could solve this problem by putting my Soundcloud / Spotify audio on a seperate audio track, but I'm not sure how to do that (I know how to create seperate audio tracks already, but I'm not sure how to do it with music tracks)
