Oshriv, to add to your corrections:
gage- I think you meant gauge
poors-I think you meant the verb pours
Song is not the only measure of commitment to Yiddishkeit, nor would I assume it is the best, although it is one way that a Neshama can express itself. But just because music does not “speak” to someone, does not mean he is not spiritual. And not everyone with a guitar and emotional music is a tzaddik, even if those songs become popular.
