Shit music, is music that requires almost no talent to produce. The genre most commonly associated with Shit music is pop music, in which artists are rarely able to play the instruments to produce the music and often deliver poor vocals. Such an industry thrives on image; records are typically sold using sex or idolising the artists.
A prime example of shit music is the Spice Girls. This group are neither talented with instruments, nor can they sing. They can hereby by referred to as a 'shit band'. However, they were popular due to their 'girl power' image. When the group split up and tried to make it as solo artists (with the exception of one) all of their careers failed as their image was lost and all that was left was their weak voices.
