RTE was quite specifically looking for 'Ireland's favourite folksong' and I think given that context it's sound to apply the usual distinction, as it is common in Ireland, between 'folk' and 'traditional' song/singers.

For every day use I think it's safe to assume we all think more in more general terms of 'songs' and singers' without necessarily applying the genre bracket.

But there seems to be a noticeable re-emergence of the F-word here in the past year or so, or am I the only one in thinking that?
