As Hart and Mould developed as musicians and songwriters, an unspoken tension and competition arose in the band between them. Tensions were heightened when Mould demanded that starting with 1984's "Zen Arcade" that the band's records contain individual songwriter credits. In spite of the creative tensions, Hüsker Dü garnered critical acclaim with the release of "Zen Arcade" and subsequent albums. Michael Azerrad stated that by 1985's "Flip Your Wig" "the two songwriters were trying their level best to outdo each other, and with spectacular results" Hüsker Dü had left the hardcore genre behind, which caused some discomfort with their label at the time, SST Records. In one interview, Hart hinted that SST thought Hüsker Dü were "soft" because they stayed in motels while touring and occasionally wrote happy songs. Hart elaborated, "We don't have to convince the world that we're suffering to convince them that we're artists... There's nothing wrong with being happy."
