I like paying for music. 99 cents to 1.29 a pop is fine, being able to pay for almost any song as a single without all the B-side ballast of a full album is a wonder of the modern age. (And then keeping access to the music, without monthly subscription fees, is also a plus, though I kind of see why some people like the selection they offer.)
Anyway, some songs I just can't find on legit pay download sites as much as I'd like to send the artists a token amount... most often stuff from other countries. (With Apple Music (or my past self hosing) my collection a bit lately, there are a few cases where I'll have to do this again) But Youtube is more international than Amazon or the Apple Music store, so when my only option is a youtube video I have had good luck with convert2mp3.net. In the past, it seemed like youtube was playing "wack-a-mole" and disabling services as they popped up, but this one has been stable and reliable for at least a few years now.
