Input: Consider Input: Question: What song on Hammer's debut album samples a song by the same name from BB King? Passage:Before Hammer's successful career (with his mainstream/commercial popularity lasting approximately between the mid-1980s until the late-1990s) and his "rags-to-riches-to-rags-and-back saga", Burrell formed the Christian rap music group Holy Ghost Boys. Some songs produced were called "Word" and "B-Boy Chill". "The Wall", featuring Burrell (it was originally within the lyrics of this song he first identified himself as "K.B." and then eventually M.C. Hammer once it was produced), was later released by Jon Gibson (aka "J.G."). This was Contemporary Christian music's first rap hit ever (by anyone), in particular by a Caucasian (Gibson) and/or from a duo. The track appeared on Gibson's album Change of Heart (1988), and "Son of the King" showed up on Hammer's debut album Feel My Power (1987) as well as the re-released version Let's Get It Started (1988). Burrell, along with Tramaine Hawkins, performed with Gibson's band doing several concerts in various venues such as the Beverly Theatre in Beverly Hills.

Input: Consider Input: Question: How many American League championships have been won by the baseball team that has played in New York since 1903? Passage:In New York, baseball is still regarded as the most popular sport, despite being overtaken by football in terms of perceived popularity (but not attendance) throughout the country, as based on TV ratings and consistent fan following for the entire season. New York is home to two Major League Baseball franchises. The New York Yankees of the American League have played in New York since 1903. Known for iconic ballplayers such as Babe Ruth, Lou Gehrig, Joe DiMaggio, Mickey Mantle, Yogi Berra and countless others, they play in Yankee Stadium in the Bronx and have won the World Series twenty-seven times. The New York Mets have represented New York in the National League since 1962. The Mets play in Citi Field in Flushing, Queens and have won five NL pennants and two World Series, thus making them one of the most decorated expansion teams in Major League Baseball. The "Subway Series" is the name used for all regular season and World Series meetings between the two teams. Before interleague play was introduced in 1997, the only instance these two teams could have played each other would have been in the World Series. The Mets and Yankees played for the World Series in 2000, with the Yankees winning the series 4–1.
