It might seem an unusual decision for a musician to release a song that wonders aloud why anyone cares that they are releasing songs. All the more so as the spotlight hits them. And then go one step further and tell their listeners not to bother with them. But “Pedestrian at Best”, the first single taken from Courtney Barnett’s debut album, Sometimes I Sit and Think, and Sometimes I Just Sit, which was released here in March, highlights just how bemused she is with her career in music.
