I think we are getting a bit far away from the intent here. The idea is to use words or at least part of words that exist in the previous post. One letter does not really constitute that. Here are the guidelines, as described by the originator of the thread.
It works like this:
You must provide a song title that contains at least one word from the previous post's song title. The artist is not part of the song title, so if the previous poster gives the artist as well, you shouldn't really use them in the next post as part of your song title.
For instance, if the previous song was I'll never fall in love again, you might post I'll Be, or Don't Wanna Fall In Love, or Love Hurts or, well, I'm sure you catch the drift.
You can also use variations of a word at a pinch. Falling for Fall, or Loving for Love, for example, is OK.
The object is not to stump the next poster. If you use a one word song title, it must be a word that is used in other well-known songs.
