David Kersh, who notched several Top 10 hits in the late '90s, is "closing the book on my singing career," according to his monthly letter on his official Web site. In part, the letter reads, "My heart is just not in the music business anymore. I can't deal with all of the B.S. that goes on in this industry now. Nothing is in my control anymore, and it all just makes me a miserable person." He also intends to shut down his Web site, according to the post. Kersh's hits include "Goodnight Sweetheart," "Another You" and "If I Never Stop Loving You."
