The song 100 Bad Days was created by AJR, a US band. The band is known for its indie-pop (独立流行乐) style. This song is on AJR’s third album (专辑), Neotheater. It tells of the sad days of an artist. “As a band, and as guys in their 20s, most of our experiences end in rejection (拒绝), failure (失败) and bad days,” the band’s three members once said. “We wanted to write a realistic (现实的) look at that.”
