MarkR, great selection. I would include some Native American flute music as well. No particular artist, but everything from South American Pan Flute to North American. I don't know why, but I love it.

Acropolis5, No issues. It is not about right or wrong, music evolves over a longer period than most people think. It is always going in new directions, but it all has deep roots. I love the variety and creativity of most all of it. There have even been some rap songs I liked, but I don't like anything (movies, books, music) that glorifies negative behaviors. Some music is political/social commentary, some is just trying to see how far off the deep end they can go. It is not just rap that does that.
