I used to use music this way, until I started noticing that when I really got into flow I wouldn't even notice if the music stopped for hours. Then I started using white noise, and eventually just stopped relying on any kind of audio aid at all. Unless you work in a noisy environment you can train your focus.
Yeah, if I am really focused I won't notice if music is on. Music is only helpful for mind numbing/very boring tasks. And helpful that those won't feel as boring, not making me do things better.
