Here is a quote by German composer Karlheinz Stockhausen about the nature and response of listening to music, taken from his book "Towards a cosmic music". I think the quote illuminates very well the many different emotional wellsprings with which music connects and asks very clear questions about why we might listen to music and different types of music.
"Music can take you downwards, upwards, sideways, lengthways - in any direction- Saying 'I love this music' doesnt mean anything at all. What do I love in myself when music pleases me? That is the decisive question. What part of me or what centre within myself, do I particularly love when I am listening to a piece of music? A single one, several, or all?"
