The influence of Australia's giant Big Day Out festival and the Triple J radio network's Hottest 100 countdown has sparked several spikes on the country's sales charts.

British acts Muse and Mumford & Sons are among the key beneficiaries of a big month of music Down Under.

Just days after topping the Triple J Hottest 100 countdown for 2009, folk-rock quartet Mumford & Sons' "Little Lion Man" (Dew Process/Universal Music Australia) catapults 16-5 on the ARIA Singles Chart, published Sunday (Jan. 31). The album from which it was lifted, "Sigh No More," this week rises 7-2, a new peak.

"Little Lion Man" topped the state-funded Triple J radio network's annual music poll when it was unveiled last Tuesday (Jan. 26) on the Australia Day public holiday. More than 1.1 million votes were cast for the countdown.

A cadre of artists converted a strong showing on the Triple J poll into sales lifts. Bluejuice rose 46-32 with "Broken Leg" (Dew Process/Universal Music Australia), electro newcomers Art vs Science re-enter the chart at No. 36 with their self-titled Green/MGM release, while Dizzee Rascal and Armand Van Helden's "Bonkers" (Liberation/Universal) re-enters the sales chart at No. 43.

Not surprisingly, recordings by those artists who appeared on both the Big Day Out tour and the Triple J poll have the most steam.

Few acts can boast the exposure Muse has enjoyed across Australia in recent weeks, and the results are clear to see in the latest sales charts. The alternative rock trio landed four songs on the Triple J chart and the band owned the headline slot on each of the six Australian Big Day Out dates, which wrapped on Sunday after playing to an estimated 335,000 festival goers across the nation.

This week, the band's fifth studio album "The Resistance" (Warner Music) rises 15-8 on the new sales chart, while the single "Undisclosed Desires" jumps 25-13. Another Muse track, "Uprising," re-enters the chart at No. 31.

Kasabian, another Big Day Out performer with three placings on the Triple J poll, enjoy a halo effect. Their fourth studio album "West Ryder Pauper Lunatic Asylum" (Columbia/Sony Music) rises 41-23.

Meanwhile, Susan Boyle's reign at the top of the ARIA Albums Chart continues into a tenth week. "I Dreamed A Dream" (Syco/Sony Music) is one of only two albums to achieve the feat since 2000 - the other is the "Moulin Rouge" (Festival Mushroom Records) soundtrack, which stayed perched at the summit for 11 weeks back in 2001. Boyle's album is certified eight-times platinum (560,000 units-plus) down under.
