I actually prefer music without lyrics and, if lyrics are unavoidable, then I prefer to listen to really strong and original singers even if they're in a language I don't understand. Musically, I came of age in the 70's and the bands that inspired me, that made me laugh and made me cry, mostly, had NO lyric interpreters, I'm talking about Weather Report, The Crusaders, Brothers Johnson, Herbie Hancock, Pat Metheny, Milton Nascimento (an exception) and others of that ilk.
The thing I find fascinating with Rap and Hip Hop, is that kids refer to it as Rhythm n Blues, which is funny, because it hardly bears any resemblance to the Rhythm n Blues I remember from the 60's. What is also ironic, is that the kids who are into it in my country, Cyprus, where there are no blacks to speak of, are white, very family oriented and very middle class and it's just so funny to see them nodding their heads to the beats and getting into the lyrics gloryfying street life, gangstas, pimps, ho's and drugs; in fact it's totally bizarre.
