It depends on the type. Brain sync, holosync and all those fancy ones can use binaurals, White/pink/brown noise music, sometimes subliminal messages etc so a compressed YouTube version of those may not be as good as it may cut out some of the inaudible frequencies and lower the sampling rate.
However personally I just prefer plain old binaural beats which are just 2 sine waves and maybe a bit of music thrown in for good measure which YouTube's compression has absolutely no effect on their effectiveness. Everyone is different but and it pays to try out a few type to see which works best for you.
Here is one example of a study/learning one, there are heaps for free if you search on YouTube.

I also find downtempo electronic music like early Aphex Twin, Boards of Canada soothes me and helps focus when I need to learn, as does classical music.
Mind you there have been many times in the last couple of weeks quitting where none of this has made a difference, but using them has still allowed me to output some work during the process.
