WOL-AM -- a Top 40, soul station -- is planning to mellow its format and shift to a more sophisticated sound. Asked if the days of rapping, black radio DJs are numbered because of the influx of new, middle-class Washingtonians who want a more subtle sound, several government officials, residents and students had these replies: David O. Leacraft, 29, director of the Now Music Ensemble, Minnesota Avenue and Benning Road NE: "Washington is on the verge of becoming more sophisticated. It hasn't gotten that way yet. But I think the election of Mayor (Marion) Barry and his shifts (from street radical to politican) kind of point that way. When I was in high school and college, I was a music major and all I wanted to do was music. As I got into more experiences, I had to get involved in more things. (I) changed my whole outlook on the radio. Now I want to get more of what's happening in the city." Wanda Barnes, 18, a Dunbar High School junior who lives at 5th and F streets NE: "I like it the way it is. The music is what's happening. I also listen to other stations. I like WOL's rap. They have style and keep something going on the radio to keep you listening to it. It keeps from boring you. There are some who may be bored by a more mellow sound." Eddie Waller, 31, painter, 4400 block of Fifth Street NW: "I definitely like WOL for the music, news and sports. They have too many commericals, but we all know you have to sell to stay in business. I think D.C. is definitely becoming more middle class. The group of people coming into the city in the last few years wouldn't want to hear WOL. That talking (on WOL) really should be cut down in a sense. Black people are smarter than what (disc jockeys) give them credit for. They don't want to hear all that stuff about pork chops and things." Greg DePass, 23, broadcast, management students at Howard University, 3rd and T Streets NW: "I think WOL should stay with the programming that they have. I listen to WOL. I listen mainly in my car when I'm driving. I think WOL is appealing to a younger market. iI think WOL is suitable. As an AM station, I prefer (WOL) over any other." Tina Barnes, 15, high school sophomore who lives at 5th and F Streets NE: "I listen to WOL. I like the music. It's nothing really special about it. I don't think Washington's becoming more sophisticated. I think WOL should stay the same." Carl Byers, 16, junior at Dunbar High School, 260 block of Pomeroy Rd. SE: "I listened to WOL once. I stopped because they talked too much. I'd like for them to play more disco music, news and I want to hear more time (reports). I think WOOK 100 is better than WOL because they don't talk a lot." Lewis Anthony, 26, assistant to Mayor Barry's executive secretary Dwight Cropp, Blaine and East Capitol Streets NE: "I stopped listening to WOL because I changed my musical habits. That type of music is no longer appealing to me. I don't think it's a class kind of thing. I also find a difference between FM stations and AM stations in the (quality of) sound and type of music. I guess WOL is all right as a high school sort of thing. It appeals to one age group. On WOL, once in a while you'd hear an editorial comment or something. It's limited in the audience it addresses." Raymond C. Thomas, 17, junior at Dunbar High School, 1000 block of Ninth Street, NE: "Most of the teen-agers nowadays want to hear more music. It's disco now. They don't want to hear too much talk unless it's something interesting. Like talks on childbirth. They (teen-agers) want to hear things that relate to them. I guess if the kids can relate to it, then the parents can learn something from it, too, and they can both sit down and talk about it."
