A young rock band are set to become the first unsigned group ever to have a top 40 hit, thanks to new chart rules.
Koopa's single Blag, Steal & Borrow is only available as a download but early sales figures show it should enter the charts inside the top 40 on Sunday.
Chart rules changed in January to allow downloads to be included even if a CD version isn't in shops to buy.
Brothers Ollie and Stu Cooper formed Koopa in Essex with their friend Joe Murphy seven years ago.
Although they don't have a record deal, they have earned lots of fans over the years through live gigs and the internet.
Getting into the charts without a record deal is really good as most bands are signed to record companies who help promote their music and finance their videos.
Koopa's manager said it was like a dream come true.
"It's fantastic. They've always wanted to be the first unsigned band to break the top 40," he said.
