Maybe she just doesn't know the music? When I read an article of that stuff I didn't have a single idea who Annie Lennox was either. I vaguely recognized the name, that's all. Only after hearing the song between all that buzz I linked it together and understood what it was about. You can't expect everyone to know every single piece of music perfectly. Maybe this song was really knew to that Kylie? It seems weird, but you never know. Don't inmediately think someone's dumb in every aspect because they don't know something don't even have to know. Poor Kylie, the world is laughing at her while she probably really didn't know anything.

When you're a music scout for a radio station? Anyway, it's just utterly funny when you do know who Annie Lennox is. Laughing about someone doesn't necessarily mean you think they're dumb. Just a bit ignorant in tis case. And she sounds like a sweet and enthousiastic person anyway, I'm sure Annie responded to her politely.
