What makes you love a song?

I agree that when I find a song that I like I listen to it over and over again. However, if I do it to much I usually annoy the whole house or it begins to where on my own nerves especially when I start singing it in the middle working or writing. I like most music including rap with the exception of some of the newer rap artist because some of the lyrics to these songs that they are singing now are not worth hearing. Sometimes I like to just like to listen to instrumental music too. Music is just one of those thing that can take you anywhere you want to go without leaving you home, car , or office.
