Buckingham Nicks on Pandora? Since when? and HOW?

[APerfectLie]

I don't listen to Pandora, but I do listen to Last.fm and the other day I almost had a heart attack because whilst cleaning my living room and listening to the Stevie Nicks station, a new song came on that I had never heard. Before the words started, I looked up to see our beloved Stevie and Lindsey on the screen and a song by BuckinghamNicks! However, this was a song I had NEVER heard called "Fantasmas". Stunned and surprised, I almost died. And then the person started singing and it CLEARLY was not Linds nor Stevie, but rather some tejano song. So I looked up BuckinghamNicks on Last.fm's website and they play a total of 6 "BuckinghamNicks" songs, but they are all the tejano songs. WTF? All the other plays that actually are BN songs were played from users own personal libraries.

However, Pandora plays all the songs from the original BN, plus the 45 version of Crying In The Night and from the previews they all seem to be STELLAR quality. What gives???
