"Olmaz Oğlan" is a pop/R&B song for the Turkish girl group Hepsi's debut album, Bir (2005).
The music video sees the girls in several dresses singing and dancing for the cameras.
They are then seen walking ponies and seen dancing on a platform in trendy cloths whilst group member Eren raps.
"Bad Penny" is the first English song to be recorded by Group Hepsi.
The beat of the song is the same as "Olmaz Oğlan", however the lyrics differ from the Turkish version.
