Are you telling me that Call Me Maybe or Friday have the exact same worth as any other song?
I didn't read any of this debate but I just wanted to chime in and say that I like both of those songs a lot - while both have flawed lyrics, they are both also deeply catchy, accessible feel-good pop songs and Call Me Maybe also has notable production and instrumentation which I really like.
Certain songs are worth more to me than others, but of course, ones perception of worth when it comes to music varies from person to person.
Back to the original topic at hand; love of composing and music in general is a huge driving force for me. Every time I felt like quitting (which has been a *lot* of times) or times where I go through a slump, listening to music and trying to reconnect with what I loved about it the first time helped. Comparing oneself to others in the sense of "this guy's better than me" is something I personally try and avoid - in my mind, "they're doing their thing, I'm just doing my thing, which is different from their thing."
