This week, West debuts at No. 30 on the Rhythmic airplay chart (viewable at billboard.biz) as a featured act on Drake's star-studded "Forever." Lil Wayne and Eminem also guest on the track, which previews the LeBron James basketball documentary film, "More Than a Game," due in theaters Oct. 2.
West's appearance on the chart isn't surprising - "Forever" is his 30th entry - but the bow at No. 40 is more out of the ordinary.
At the Rhythmic chart's anchor spot, Taylor Swift crosses over with "You Belong With Me." The song topped Country Songs for two weeks and has reached the top 10 on the Billboard Hot 100, Pop Songs, Adult Contemporary and Adult Top 40.
How rare is it for a core country act to cross a hit from its home genre to rhythmic radio? Since the Rhythmic chart's October 1992 inception, only two other country acts have scooted onto the survey, and both did so in 1998.
Aided by a dance remix, LeAnn Rimes ' "How Do I Live" rose to No. 22 on Rhythmic in February 1998. The song spent 11 weeks atop Adult Contemporary in 1997, besting its No. 43 peak on Country Songs (where Trisha Yearwood's version of the ballad climbed to No. 2).
Five months after Rimes' peak on Rhythmic, Shania Twain 's "You're Still the One" reached No. 20 on the list. The cut had topped Country Songs for a week in May 1998.
An honorable mention goes to Tim McGraw , who occupied the Rhythmic roost in November 2004 on Nelly's "Over and Over." That song, however, never charted on Country Songs. And, Jewel  reached No. 30 on Rhythmic with "Foolish Games" in 1997, long before she segued to recording country music.
'TRACTOR' PLOWS ON: On Country Songs, "Big Green Tractor" won't budge, as Jason Aldean 's title leads for a fourth frame.
Aldean's song logs the first reign of at least four weeks since Brad Paisley 's "Letter to Me" ruled for four frames in February 2008. With his latest week at No. 1, Aldean ends the longest streak of songs to spend between one and three weeks at No. 1 since Country Songs converted to Nielsen BDS-monitored airplay in 1990.
No track has spent more than four weeks at No. 1 since Taylor Swift's six-week stand with "Our Song" began on the Dec. 22, 2007, chart.
Paisley, meanwhile, posts his 22nd top 10 on Country Songs, the fourth-best sum this decade, as "Welcome to the Future" lifts 11-10. Should the title reach the top, Paisley would extend his streak of consecutive No. 1s, which began with "When I Get Where I'm Going" in 2006, to 11.
MUSE'S ALTERNATIVE 'UPRISING': British trio Muse  celebrates its first No. 1 on Alternative Songs, as "Uprising" vaults 3-1. The band performed the song on the MTV Video Music Awards (without any unexpected interruptions) Sunday (Sept. 13).
The group had previously climbed as high as No. 2 with "Starlight" in 2007.
Muse's fifth studio album, "The Resistance," will bow on next week's Billboard 200.
Jay-Z's latest coronation pushes him past Elvis Presley  as the solo act with the most No. 1 albums in the tally's 53-year history. Among all artists, only the Beatles, fittingly, with 19 No. 1s, have more.
