As a conclusive idea, you might say that, try to listen to the bass lines. they will give you the chords 90% of the times since they are most of the time not very complex(though a lot of exceptions exist) and bass riffs are based on connected root notes of chords.
So if you have a bass note, and need to get the chord, try all maj,min, 7th, 9th, aug, dim, sus2, sus4 till you get the perfect chord. It all about listening and concentrating.
I always thought the good thing about the guitar was that they didn't teach it in school.
