Pete, Jake, thank you for the replies
I'll start from the records, that's the part I forgot to explain ;-P
Unfortunately, even when I did have a contract with the German label Syngate, all I made was something like 600 euros a year... That's not even enough to survive one month.
People do not pay for music, they can have as much music as they want with just a (legal or illegal) click
The point is, selling my music wouldn't give me enough to live on, so I would still need a "real" job, and the side effect would be that my music couldn't spread freely as it does now :-/
Plus, what I do is not "commercial" - for example, I'm on bandcamp, but I get in a year the number of hits I get in three weeks on my own website... it just doesn't work for my kind of music, which is basically just for a niche :-/
Finally, there's my personal take on it... I think one should keep some things as "pure" as possible. Promoting and selling it would turn it into a job... I'm not sure I'm getting my feelings across, what I mean is that when I make music now, it's just for it to exist, period. The moment it became a "job," it'd stop being my share of giving to the universe in return for what good I've gotten in my life... I know it sounds crazy, but you can probably understand.
However, I wouldn't have any problem with producers of anything using it for their own productions, but I would definitely need to make some money out of it. No royalties, at least initially, a single payment would be OK, but I do need it.
Throughout my life I've used, at different times, all the things I can do and all I am, but I've never tried to make any serious money with music, which happens to be the one thing I can really do.
Maybe it's just because I don't really know how I will survive now that I don't have a job anymore (and won't find one anytime soon), so my mind has come up with this crazy idea for me to focus on in order not to let me get truly desperate, but I still think it's worth trying...
So yes, Pete, whatever lead you could give me to follow - as long as there's a little dough in it - would be just great
Thank you again for your replies!
