Music is basically melody, harmony, and rhythm. But people can do much more with music than that. It can be very descriptive in all kinds of ways, all walks of life.
I think the melody is the first time I hear in a song and if I like the melody, then I'll pay closer attention to the lyrics.
Ever since I was a child I've always been very attracted to melodies. Whether I hear Jeff Beck, a choir, an ocean or the wind, there's always a melody in there.
