Yes i have this habit from my age of 13 still now when i have exams or night time studies i always use to listen songs parallel. because songs make me feel fresh. Normally i put a headset and in less volume and read the things if i get bored i increase the volumes. Normally i have 2 playlists one is melodies and another one is fast beat. When i am normal melodies in boring fast beats. For me it's workable nearly 10 years.Not only studies if i am going to do something quickly i listen songs parallel.
