yep...what you write is 'songs'....and if they have a certain 'feel',50-60 years from now, if they are being sung by people who barely know, or DONT know the author, they may be considered 'folk'...even if not, they may be famous and well loved...In this age of keeping records of everything, it would be hard to leave totally 'anon' songs behind, If Bob Dylan becomes 'folk', he will be like Woody Guthrie, whose name is connected with most of his stuff. Now, not all of Woody's stuff may be considered folk, and certainly not all of it is GOOD...but he will have a few things that will go on forever...probably.
