"for the 17th- Traditional and recently released."

Umm, what is the 17th traditional and recently released?
Surely the traditional songs have been done and done again by any amount of artists? Why the emphasis on 'this years' trad. release?

I'm asking as someone who doesn't necessarily recognise the particulars of popular American-Irish music, which is what I presume you must be refering to as opposed to traditional Irish music? Or am I wrong?
