Hmm... i'm guessing you're meaning some song that is outside of you usual genres of interest. Black Sheep, which is a rap group... I think from the early 90's I love them. Its just because they're clever and I can enjoy them because of how clever they are sometimes in their lyrics.
A particular song... hmm... a lot of songs get to me. Hmm... well I guess the most recent would be a classic rock song... "dust in the wind" you all know who its by I image.. Kanssas. I've had a general distaste for classic rock for a while, just because I've heard it all so much. I heard that song one night on the radio and now I'm a little addict of the song.
