Keith Caulfield answers readers' questions about Kylie Minogue, research and charts.


Hello Hello.

Kylie Minogue is set to do a greatest hits tour in Europe. Is there any chance of a few shows in the United States?

Hi Mike,

Pop songbird Kylie Minogue kicks off her Show Girl tour March 19 in Glasgow. The trek winds its way through the U.K. and the rest of Europe in April and early May. Currently, she has not announced any U.S. dates for the tour.

As previously reported on, Minogue is releasing her greatest hits set, "Ultimate Kylie," Feb. 1 in the United States via Capitol. The two-disc effort spans her entire career, reaching back to her early days when she scored hits with "The Loco-Motion" and "I Should Be So Lucky."

The colleciton also includes the new single "I Believe in You," co-written with Jake Shears and Babydaddy of the Scissor Sisters.


Hello Keith,

I was just wondering if there is a resource to see Billboard's history of weekly top 10 album sales.



Hi Nathan,

Well, your best for any research-oriented questions of this nature is Billboard's Research Services which can be contacted or 646-654-4633.

For a small fee the Research Services department can assist you with an array of chart based questions -- everything from what was the longest running No. 1 of 1990 to every top 10 album for the past 40 years.


Hello Hi Keith,

Do you know what the most popular No. 1 pop/rock song was for 2004? How many weeks was it No. 1?


Hi Mark,

I'm not sure I completely understand your question, but I'll take a shot.

The easiest answer would be Usher's "Yeah!" featuring Lil Jon and Ludacris. The track spent 12 weeks at No. 1 on the Billboard Hot 100, which covers all-radio formats. Essentially, that means the chart ranks the top 100 songs in the country from all musical genres -- everything from pop, R&B, hip-hop, Latin, country and so forth.

"Yeah!" spent the most weeks at No. 1 on the Hot 100 and was No. 1 on the 2004 year-end Hot 100 wrap-up.
