Can we identify specific emotions on the basis of fMRI scans? I am looking for fMRI studies in which the emotional response of a person listening to music is visible in the fMRI scans, paralleled by a retrospective think aloud report of the person describing his/her emotions while listening. Are there such studies? And did they reveal something comprehensible, i.e. can one see in the fMRI scans how emotions did manifest themselves?

The idea is, that one might be able to distinguish between emotional responses due to characteristic activity patterns or modes, perhaps including the amygdala. 

I know of this video with Oliver Sacks being the person, but it disappointed me: we only see that he is emotionally touched stronger by Bach than by Beethoven. But - as I have the impression - we cannot distinguish between positive and negative emotions by just looking at the fMRI scans, can we?
From meta-analyses that include musical emotion inductions, there is not much evidence that we can reliably distinguish between emotions in the brain, independent of the emotion induction procedure or meta-analytical method (1 2 3 4 5).

We might be able to distinguish emotions with specificity and reliability within an individual, but this kind of work is just starting to happen.
