I don't understand oo, when you see something that is good will you not know? I'm not really comfortable with that statement, "it's your". We should be able to see what is good and accept it. I'm not saying cool music is not okay, I'm only saying that there are different songs for different times.
When you want to meditate, cool songs are there for you, when you want to be more lively, it's advisable you play something loud, like a pop or rock song, in fact that's one of the reasons we have different genres of music.
We don't have to say it's based on our choice, there is time for everything. I don't play loud music all the time because I'm not free all the time and even when I'm free, I sometimes play cool songs too.
