The 10 finalists from the second season of "American Idol" will release a charity single, "What the World Needs Now Is Love," with a portion of the proceeds going to the Red Cross. RCA will release the single April 15, the same date that "American Idol" first-season winner, Kelly Clarkson, releases her debut album, "Thankful." "What the World Needs Now Is Love," written by Burt Bacharach and Hal David, was originally a hit for Jackie DeShannon in 1965, when it reached No. 7 on the Billboard Hot 100.

"American Idol" has been a ratings winner for the Fox network, with the second season currently averaging over 20 million U.S. viewers per episode, according to Nielsen Media Research. On April 29, RCA releases "American Idol Season 2: All the Classic American Love Songs," featuring cover songs from the season's finalists.

Meanwhile, the 20th Century Fox feature-film musical "From Justin to Kelly," starring Clarkson and former "American Idol" finalist Justin Guarini, has had its release date pushed back from April 25 to June 13. There will reportedly be no soundtrack for the movie, but Guarini's as-yet-untitled debut album on RCA is expected to be released sometime in June.
