In the Billboard "Hot Dance Club Play" chart dated 23 December, Runaway is a new entry at number 38.  Billboard.com only gives chart positions 1-25, but the complete chart is available elsewhere...

For info, in 2005 Feels Just Like It Should made it to number 1 in the Billboard Hot Dance Music/Club Play chart, and before then, You Give Me Something made it as high at number 2 in 2002.  More Billboard chart positions for the band can be found at the Jamiroquai artist page at Billboard.com.
