Question

Do plants really respond to their surrounding (i.e music), and if so, how and to what extent?

Answer 1

Yes they do respond to their surroundings, have seen plants that don't like each other grow away from it's neighbor and others will entwine their branches.  Plants love music but hate traffic noise if you place a partial shield to the traffic noise, the plants that are behind it will grow and the others only do half as well.

Answer 2

Mythbusters tested this, talking to your plants supposedly does help them grow better. But playing music for them is even better for them, while testing plants (they were either pea or bean plants) their results showed playing heavy metal music for your plants yielded the best results. Believe it if you want I thought it was cool.
