So the day after I uploaded this part, I go to my YouTube dashboard and find out that the video has been copyright claimed because of the last song I used. The claimant was fine with me keeping the music in; it's just that they would get any money from ads. The funny part is that all of my vlog parts have been unlisted and non-monetized, so what's the deal? How'd this one get claimed, and all of my other videos are fine? Doesn't make sense to me.
Anyway, you know the drill: wear headphones, and allow me to give credit where credit is due, musically speaking.
