You can only use words from a name to make another name and words from a song to make another song.
Starting from here:
September - Earth Wind &Fire
The Rules:
Use the previous song to pick a new song by using a word in from the song title or the artist's first or last name:
Ya'll don't have to go strictly by the song name if you don't want to. You can go by the person's name too. For example: if you had whatever song by "Marvin Sapp" the next post could be whatever song by "Marvin Winans" then the next could be whatever song by CeCe Winans. Just puttin' it out there.
Well according to these, this makes it slightly vague. you must admit, it opens up the opportunity for much more creativity which has been greatly demonstrated. But, it is your game.
