As I'm Modding the Forum, I get to see many, many topics and posts, often enough with some musical recommendation or other. There's not enough hours in the day to really listen to 'em all, or even a selection, but there are times where either the post is particularly appealing, or I've a few minutes 'spare' while my tea cools or whatever. In this fashion, I've come across a few real gems that I would never have met in any other way, and maybe just as many that I can't believe anyone would spend even a few seconds on. On occasion, I've even gone as far as to make a remark along those lines; this obviously curries no favours with other Posters, but that's Forums for you..!
My only other source of new listening is France Musique, a 24/7 'classical' national music station. I say 'classical', as there are often enough 'jazz' pieces played. I have this on with an hour's timer when dropping off to sleep; sometimes I'll hear a few minutes, at other times I'll re-set the timer as I'm still awake when it turns off. I hear no 'pop music at all, and miss none of it, as the few brief snippets I come across inspire me not one jot.
Oh, yes, another source would be the monthly Composition Challenge, whereby I'll listen to (sometimes several times over...) the entries. These are very varied in genre, but are, for the most part, of high compositional quality. I'm excepting, naturally, those that turn out to be EDM 'head-bangers'; these do not get a second spin..!
