The digital broadcaster Amazing Radio - a radio station dedicated to playing unsigned and independent music - has launched a new weekly chart for unsigned bands.

'The Amazing Chart', a Top 40 exclusively dedicated towards highlighting unsigned acts on Amazing Radio, will be aired by the station at 5pm every Sunday, with a run down of the top 20. The top 40 will also be published online by Music Week.

Chart positions will be determined through a mixture of airplay on Amazing Radio and the popularity of tracks on amazingtunes.com, Amazing's online music site. Any unsigned or independent artists who upload their tracks to the site will be automatically eligible for the chart.

Listeners and hopefuls can tune into Amazing Radio here.
