I've never heard a song nearly as audibly offensive as either of these. Its not that they're bad songs, but they just sound awful... liking a squeaky chalkboard.
Okay, "Deck the halls/Bust a move" could work... but whoever made that track needs to be shot in both ears... and maybe a few fingers should be amputated.
The girlfriend thing is an awful idea; its childish while they're trying to sell a phone for "professionals". The voice in that should be autotuned, and then autotuned again for a safe bet.
I'd rather watch a straight hour of overly pleasant Apple commercials than 5 seconds of either one of those atrocities.
