My most common reading times are during my lunch break at work and before work if I wake up earlier than I need to be awake. But other than that, I just read in little bursts throughout the day when I have free time.
I prefer eBooks over physical books because they're easier to hold, have adjustable font sizes and themes, and I don't need a light to read. This is nice when reading before bed so that I can read my book in the dark, with light text on a black background. It's also nice that I can read practically anywhere since I almost always have my phone or some other device on me.
I don't play music when reading. I prefer a quiet environment.
