Your bad habit is only 'bad' because it slightly annoys you?
Not for any other reason?And apologies as I've confused myself a bit here with the definition of 'habit', so:
Does the habit require using your...Ears? This one.
Do you listen to: music? I assume you mean the habit - in which case - yes.
You bad habit is the act listening to music?
...and therefore it involves your ears because you use your ears to listen to music?
My bad habit is related to listening to music.
Your bad habit is not the act of listening to music itself, but is something related to you listening to music?
...something triggered by your listening to music you like?
...and is something that you do while you listen?
...or is something that you do after you listen?
...and it is this other something that involves your ears?
Or are you defining your bad habit as a "combination-of-both-listening-to-music-and-also-something-else"?
