"However I have already paid to go and see someone who played it, and this was certainly part of my decision to do so. They've probably made more money off me from that than they would have if I bought the flac."

Who's the "they" there? The DJ who played the track or the artist who produced it? Sometimes it seems that in electronic music DJs get more attention/credit/$ than the artists who made the tracks being played. (although I know some DJs are also producers as well, I think they're the exception to the rule)

Could be both, often it would be a DJ who is on the same label or part of the same crew as the producer who wrote the tracks. Often these people share studios, so there is a direct monetary link there.

There are almost no DJs who aren't producers. The few that are only DJs either have some special and unique facet to their style of mixing, or they date back to the early days when Things were Different.
