Haha, I used to harass bands I loved as well. Like you, I got mostly positive and polite responses. I suppose my emails were constructive and kind so they appreciated it and reciprocated to some degree.

I learnt a fair bit about music from some of these exchanges. It was good fun. A relic of the old internet says I guess. These days you’d just look for content on YouTube or something instead. Still awesome in its own right, but different.
