The legal molasses in which MP3.com
is mired got thicker and deeper in mid-March, when MPL Communications launched a lawsuit against the Internet music company. MPL, ex-Beatle Paul McCartney's publishing house, joined the attack begun months ago by the Recording Industries Association of America
. McCartney's firm filed suit in a New York US District Court against the San Diego–based startup over copyrights on intellectual properties owned by MPL, whose catalog includes McCartney's solo work, as well as the works of Buddy Holly, Hoagy Carmichael, Sammy Cahn, and other songwriters and performers. MPL was joined in the suit by Peer International, which owns the work of the late Latina star Selena.
