I've seen these "stream everything" that ever been recorded web services and I've not signed up to any of them.
Partly it's because I wish to own physical copies of music that I can play when or where I like (and lend to whom I like), on whatever devices I like and not have to gain permission from or pay rent to some giant corporation.
Partly, it's because I'm not sure what they are offering is of real use to me as a musician. All recordings? If that's even true which I obviously doubt ... why?
No, I do know the attraction, you can look up all sorts of stuff and follow up things that people mention to you etc, but how can you possibly listen to "everything"? It's a consumerist nightmare, where do you start or finish as a traditional musician who wants some kind of roots? And, yes, I am aware that I am also a living/playing contradiction in all of this
To my mind, it's an offer that should be viewed with extreme circumspection. I once listened to the same CD for over a year, 5 or 6 days a week both ways on a commute through the centre of London, and I was still not tired of it by the end of that time. Tunes from it still pop up at random as they do from other well played recordings. It was a Patrick Street CD if you must know ...
Maybe that sort of thing is too extreme for you. It was initially because nearly all my belongings were in storage at the time, and my options to begin with were limited to one random CD, and then it just sort of went on that way.
Of course I listen to all kinds of things on Youtube and TG4 and get the occasional new CD, but there are numbers of recordings that I keep going back to, time and again ... with no advertising, tracking, recommendation algorithms or rent to pay.
It's like playing with the same people for years in sessions, which is incidentally where I've picked up the vast majority of the tunes I play. That and dancing to ceilidh bands and the Morris.
I was going to make a short list of recommendations, but if I make only one (Denis Doody, "Kerry Music", Mulligan Music 1978) maybe that will do and you'll end up listening to it every day for the next year or so and learn all your other tunes from contrary sods sitting in sessions
ps. disagree with me and do whatever you like of course. I'm just musing.
