Many components make up a song: the song format, genre, rhythm and tempo, melody and harmony, lyrics, the catchy phrase, the instrumental break, etc. Maybe it just comes down to a photogenic personality they can market. What do you think is most important? Or, can you grade different components with levels of importance? For me: I'm more of a lyrics based songwriter, and a legend in my own lunchbox. (Read as not successful) However, considering the quality (or lack thereof) in so many promoted and played songs, I feel there are aspects given far more weight and importance ....... like when I've heard the same phrase repeated 30 times in the one song, I'm tired of the phrase before the song has ended. Should I perhaps give more weight to the rhythm and tempo? Should I be trying to hypnotize the audience with a repetitive phrase?
