For the Love of Music

Today I feel like discussing music, so here I go.
Music holds a lot of power over my mood. For example, I really do not like country music (or overplayed radio hits. These are really the only two genres that I can't stand to listen to.) The cleaning lady on my floor, however, really seems to enjoy listening to the country radio station VERY LOUDLY in the morning as she cleans the floor bathroom. This occurs at about eight thirty in the morning, which is not an ideal time to have country music blaring up and down the hallway, so needless to say if I wake up to country music, I'm automatically set to have a bad day.
But after having had said bad day, if I come back to my dorm and put on some music (I find the Beatles' Abbey Road to be particularly soothing), I'm almost instantly healed of my unhappy day. I like this effect. It is useful. For example, if I'm not feeling motivated about writing a paper, Family Force 5 will remind me that it can be exciting to write. (Actually, Family Force 5 just puts me in a go-getter mood, which is much better for writing papers than a Janis Joplin "please let me ignore this world" type of mood.) If I feel like giving the world the finger, I put on Cold War Kids. If I'm feeling spiritual I listen to George Harrison. Japanese pop, as a rule, makes me feel like giggling and wearing neon colors. I could go on, but there are a lot of artists/music genres and a lot of moods to catalog.
What I'm wondering- is everyone affected by music in this way? How differently do people feel about the same songs or artists? How universal is music?
I feel like these are old questions, but still. I'm curious.
