I'm with Joe, I don't think he called Steve Earle "of no significance" the song is not of historic importance and is readily available on other sites which he has generously pointed out. I like the song and sing it but won't claim it to be something that it isn't.
It certainly does not have an old timey feel. If I was looking for a label then I guess Honky Tonk would fit it better and there ain't nuthin' wrong with that.
