Just for the record, the guys I listen to are James and SouthPaw.
But anyway, 30 or 40 songs is really not that many from a chord perspective. What you'll find is that almost all songs are made up of some variation of the same set of three or four chords. The rhythm may be altered and the lyrics will always be different, but you're going to find yourself playing the same chords in one variation or another for almost every song.
So learn these sets of chords, and you'll have three or four thousand songs nailed cold.
