Miley Cyrus' cover of Arctic Monkeys' 'Why'd You Only Call Me When You're High' has leaked online.

It was recorded as the encore of her 'MTV Unplugged' special but it didn't air, since it was probably more prudent for the network to have the hour-long special close with Miley's duet with Madonna.

It's an interesting cover choice, that's for sure. She hits some power notes.

Here's the original, in case you are not familiar and only made the introduction to the English rockers due to Miley. The band's elitist fans might not appreciate Miley having her way with the song, but we think she did a rad job. Just listen to the last few seconds of the song, where she lets it rip. That's all the proof we need.
