100 or 200 years from now, some songs that are being created today will have survived and become "traditional" and/or "folk." Their authorship may or may not have been forgotten by then.

Which category of contemporary songs is likely to yield compositions that will survive a century or two of folk-processing?

1. Popular, commercially-recorded hits?

2. Creations of the much-berated "singer-songwriters" working in the "contemporary folk" or "acoustic folk-rock" genres?

3. Songs written by 21st-century trad-folk performers trying to emulate the style of some earlier time?

I'm just offering this as food for thought. My opinion is reflected in the order in which I wrote the above three proposed categories, but I understand that others will feel differently.
