RE: A lot of 'Singer-Songwriters' seem to sing the same song, slightly differently...

I agree that there are more than few individuals, who perform their own songs, that don't seem to produce much of a variety in their tunes or lyrics... which makes for a very long & tedious set when they don't sing anything other than their own works. Hubby referrs to this as "and then comes that dreaded phrase, " and then I wrote...".   :)

There is nothing wrong with performing your own music... and titling yourself a singer- songwriter. And there is certainly nothing wrong with writing within a certain style... just keep in mind Sturgeon's Law... " 90% of everything is "@rap"... and maybe not everything that makes it onto the paper is all that great.
