I don't know if the word 'obsession' can be related to music for me, but it's definitely a very large facet of my life. If I can, I'm listening to music every chance I get. So unless it hinders with what I'm doing at the time (studying, watching a movie, etc.) then yeah music is going to be blaring. Sitting at my computer, music is always on and I'm usually multitasking, searching for some kind of new band or genre; if I'm taking a shower, I've got a playlist on; if I'm doing yard work, I've got my headphones on full blast; if I'm driving, you can bet your ass that car is bumpin'. Boom boom. I love music, and I can't exactly see how it can be an obsession in terms of being 'addicted' as some have mentioned, but it definitely has manifested itself in a way that has encompassed my life, though for the better. Nothing drastic, but certain bands or specific songs have shaped my life in little ways that add up over the years. It's hard to imagine that in my younger years, while I grew up with many influences that molded what I listen to now, I didn't have any interest in music at all. I didn't even buy my first CD until I was in highschool (Metallica - MOP, lil' tidbit). While I can't say that I 'couldn't live without it', it's accurate to say I can't 'picture my life' without music; it'd be a very hard transition...very, very difficult.
Suffice it to say I've let music take over a portion of my life; it's certainly apart of who I am now. Though I'm not looking to date and I am enjoying the single life to its utmost potential (oh and SCREW FEMALES, YOU DIRTY VAGINAS), I can say now with only a slight cringe that if someone I'm dating can't bear to listen to the music I listen to or at least let me have my time to rock out, the relationship wouldn't work. So yeah...knowing that somewhat pathetic fact, I think it's safe to say that music is, in some way, my beloved obsession.
