Question Music stutters when alt tabbing

[TheBoax]

Whenever I'm playing a video game, League, Modern Warfare, and I have some music in the background such as Spotify or Youtube, everytime I try to alt tab, it stutters for like 3 seconds. I'm honestly not quite sure when this started occuring but I don't think its any component bottlenecking thats causing it. Here are my specs: https://pcpartpicker.com/user/TheBoax/saved/#view=3N3W3C

I've already checked my Task Manager and there is no overload on the CPU,RAM, or GPU whenever I'm alt tabbing.
