@bdp24 - I don't know how old you are, but I can assure you that back in the late 60's and early 70's, 'singer/songwriter' was a VERY popular style of music among people my age, who were teenagers. Elton John, Rod Stewart, James Taylor, Joni Mitchell, Jackson Browne, Don McLean, Johnny Winter, and I could go on and on.
Today, all you have to do is look at the pop charts and I think you might see more individual names than band names. Guitar-based rock bands have not been the most popular genre among younger folks for quite some time now. Hip-hop, pop, and electronica rule the roost. Doesn't bother me either way.
