For me, lights are usually dimmed and/or curtains drawn. Sitted at the sweet spot, ears at tweeter level and then just immerse into the music, listening through the whole album unless an odd track really urgs me.
I am often on the computer as some would have realised, on this forum, reading about music suggestions amongst other topics, researching and exploring such as reading about Maria Callas yesterday while enjoying her work. Computer fan is at the lowest setting or off to avoid distraction. Like @Dashing, I usually have a coffee with me and grab a snack between albums.
While I don’t like being distracted while listening, depending on what I feel like and listening to, I might get out of the sweet spot, move around or even sing along - the very thing I hate most from others when I am listening.
