Do you listen to music mostly with headphones ?

For me. genre plays a big part in how best to listen to something. Claissical, Progressive stuff like Early Genesis, Tangerine Dream, Floyd, Oldfield, or even Dream Theater are great with 'phones on, where other styles are best through speakers and loud, more closely approximating a live perfromance.
The environment you listen is also a huge factor. On a walk through the woods, Lemmy blasting from a boom-box probably doesn't work well...
