Term for a band/group that has one breakthrough hit that people remember after usually years of making underground music. They may try to luanch more chart-friendly songs on the back of their one song that will fail to have any impact. Will fade back into obscurity within a month only appearing for the odd television appearance.
The ultimate one hit wonder were Los
del rio who inspired a massively popular dance to go with their
catchy song; La
macarena!
