She didn't write the song...Mike Boone said:schan1269, if you were a teacher, I'd say that you were a very, very generous one, in assigning grades, to the work that you judge.
The presentation of Too Young to Fall in Love, that I heard on your post, has one or two interesting lines of lyrics, along with one line repeated far too much, and all of them, sung by a young woman with a fairly good voice. But calling the song brilliant, is a really big stretch, IMO.
To me, that song simply doesn't seem like one that such artists as Adele, Joni Mitchell, or Tori Amos, would be proud to list as one of their compositions.
Motley Crue did.
The briliance is the direction she took the song.
