An Indiana songwriter is suing Britney Spears for copyright infringement, claiming he wrote the song "Sometimes" 15 years ago. In court papers, Steve Wallace says he shopped the ballad around to publishers in 1994 and submitted it to a lyric contest in 1997. He also claims to have a copy of an e-mail from Spears in which she confirms that Wallace is the song's author. The e-mail also allegedly confirms that Spears can't spell.
