1: Music only sometimes triggers an emotional response itself.
Often, the situation in which the song's first encountered (or first 'listened to') is what you build a memory out of which that song can trigger. Example: lilmissnever has a very idiomatic set of responses to some songs, and they are not songs I'd've thought of myself, for the same answers (and indeed, even knowing at least some of who they're 'about') -- and I've learned a bit about her, as well as gaining a new perspective on those folks, from reading her answers.
2: Solsbury Hill is apparently a rather impressive tune.
That's the only one that I can look at and sort of think it's speaking to the emotions, rather than acting as soundtrack to the situation.
3: Sometimes, the influence you've had on people's musical taste is more than you thought it was.
