Personally, I prefer not to try and divide all the music into little category-boxes, although I understand that's often necessary for marketing purposes. I like having the new bands listed in with the old classics (and old obscurities); it encourages people to try something new (or old) that they might not otherwise hear.
I wouldn't even put the Country & Western off in a cowboy ghetto; Carlene Carter may be country but she's backed up by Graham Parker's backing band. Meanwhile, the New Riders are playing pedal steel licks that are far more country than anything the Rumour cooks up. It's all music, I just like some of it more than the rest of it.
