The greatest memory for me of the 1984 Olympics was not the individual honors, but standing on the podium with my teammates to receive our team gold medal.
I think it's important for artists to work together. It's great for fans to see, like, Ludacris came out to our show in Atlanta and kinda made a surprise appearance there, it shows a mutual respect for what each other does.
I understand that transposing a song a half step can effect the believability of a lyric.
