Not sure, if worst coding interruptions, but these come to my mind as I'm listening to music while coding on Windows, because I kind-of have to.

1. Some shitty song coming next on the Discover Weekly on Spotify.

2. Windows freezing/slowing down randomly

3. IntelliJ freezing on Ctrl+click/Ctrl+B while I'm thinking on something complex, because our project is huge.

4. My video card driver crashing randomly at startup, so I cannot use my monitor through HDMI
