Ramsey earns his first Hot Country Songs hit, while Nelson notches his record-extending 51st top 10 on Top Country Albums.
Mason Ramsey, the 11-year-old who drew viral buzz after yodeling at a Walmart in Illinois, debuts at No. 4 on Billboard's Hot Country Songs chart (dated May 12) with his debut hit "Famous."
The song launches at No. 2 on Country Digital Song Sales with 19,000 sold in the week ending May 3, according to Nielsen Music, while drawing 10.8 million U.S. streams.
Ramsey, who discovered country greats like Hank Williams Sr. by sifting through his grandfather's album collection, follows other young performers over the years on Hot Country Songs, including Tanya Tucker, who was 13 when "Delta Dawn" reached No. 6 in 1972; Marie Osmond (14 when "Paper Roses" hit No. 1 in 1973); LeAnn Rimes (13 when "Blue" climbed to No. 10 in 1996); and Billy Gilman (12 when "One Voice" hit No. 20 in 2000).
