It's a point of principle about Seth's song being nominated as 'traditional'. It has been pointed out that the song is not trad (and Seth himself agrees). So why hasn't it been removed from the nominations? That's all we want to know - this is the issue.

If the BBC / Smooth Ops refuse to answer this question, they imply that any song could be accepted (whether written 500 years ago or this year) as 'traditional'.

(Whether the song is 'good', enjoyable to listen to, etc., is another question, and entirely subjective, so doesn't help resolve the above issue.)
