::My comment above was probably a bit too sweeping, sources like blogs can be acceptable; I suppose the point I was making was that they need to be used with caution, and you would need to be prepared to argue your case in a quality article review. I think what I was getting at with the "beautiful song", was that a non-neutral phrase would be helped by a reference, not that it should necessarily be removed. A US editor, say, might see the statement as obvious pov at FAC.  -
