Rizzle Kicks can't afford to put out the songs they recorded with Pharrell Williams.
The duo worked on a number of tracks with the producer for their last album 'Roaring 20s', though they weren't included on the finished album and now Pharell has seen his career skyrocket thanks to songs such as 'Happy', 'Get Lucky' and 'Blurred Lines', his fees have soared so the 'Down with the Trumpets' stars are unlikely to ever use the material.
Harley Sylvester said: ''They're just gonna be way too expensive to use.''
Jordan Stephens added: ''It's a shame but it was my call not to put them on the last album.
''I stand by it. You can't put a price on something that's in the universe for ever.''
The pair showcase a more disco sound on their new single 'Tell Her' and admit they have become disillusioned and uninspired by the current rap scene.
Jordan told The Sun newspaper: ''I'm definitely not going to stop rapping, but at the moment rap as a culture just kind of does my head in.
''I'm not listening to it any more. In the UK I hear a lot of imitation of US rap and I don't feel inspired by it.
''And more importantly, rap has taken a decline in terms of its mainstream appeal.
''I started to realise I can sing. It's liberating, it's an evolution and it's fun.''
