Listening to music while meditating
Listening to music, among other liminally conscious activities, like scribbling or tapping a pencil while listening to a lecture in class, are ways of distracting one’s attention from other more disturbing phenomena such as street noise, but the goal of meditation is to focus the mind, not distract it. I suggest that buying some industrial grade earplugs (not the foam kind) would be more beneficial to your practice than listening to music.
