Lee believes his things have "sincerity" and can't avoid making an impression--they are not done carelessly. Landy Chang, who understands Lee well, says "his work is thorough, his concepts complete; every song is listen-able."
縱使如此，李宗盛認為他的東西「一定有『誠意』，不會不深刻或草草了事」，對他瞭解極深的張培仁表示，小李的作品「工很細，概念完整，每首歌都有可聽性」。
