Generally, I hate them. But it depends on the lyrics and tune. I'm fine with MCR's rendition/ version of All I Want for Cristmas is You. But I don't like the non-rock versions. And, for original songs, my only fave is FOB's Yule Shoot Your Eye Out. I like Xmas songs with a diff. kind of message.. not the same old stuff. :)
some of them I do
My favorite is the one that I sang in as a background singer. The song is called "Elvis the Elf"!
Here is the link if anyone wants to see it :)
It depends on the song.
