She sang with Billy Idol and it was not bad at all. She has a raspy tone which I think exacerbates her "over performance" somewhat. That said, she's a hell of a lot better than taylor swift who sings flat as hell (or whatever your imagination brings to mind). That said, miley is no Gaga. As much as I hate Gaga's politics, she is actually a damn good vocalist with much more range than miley and adele.Not too bad, Having seen Blondie in person Miley did the song well, true to her form she could have toned the vocal effort down a little. Thats one of the things I dont like about her, aside from being an idiot.
However, seeing this performance underscores how good those folks in the 70s and 80s really were...before autotune.
