US pop artist Katy Perry continues to dominate the singles chart at Last.fm for the ninth consecutive week with her hit "Teenage Dream." Rihanna moves into second place with "Only Girl (In the World)" while Lady Gaga's "Alejandro" holds third. Also this week: Bruno Mars maintains his place in the top ten.

New in the week's top ten is Perry's track "Firework," the third single from her album Teenage Dream. According to Perry, "Firework," with 23,315 listeners this week and jumping 16 spots into number six, is influenced by Jack Kerouac's novel On the Road. The track hasn't received the international success of "Teenage Dream," and has so far reached number ten in the US Billboard singles chart and number three in the UK singles chart.

The lead single, "Just the Way You Are," from Bruno Mars' new album, Doo-Wops & Hooligans, remains in the top ten this week with 21,567 listeners. The track, released in July, has become an international hit, topping charts in the US, UK, Australia, New Zealand, and Ireland.
