RoMee187 :
1) Any MP3 from youtube is low quality garbage, it's like watching VHS movies or playing games at 9fps.
2) Get Foobar
3) Get some good 24/96 flac
4) Enjoy Hi-Res music.... In PC nerd language, Enjoy 4K gaming.
Most Phones and MP3 players wont read Flac as well as the size is limiting unless you have a huge amount of space. 320kbs is a great format for mobile users, the file size is good and the sound on the average pair of speakers and headphone is enough to satisfy nearly everyone.
For downloadable Legal Free Music of decent quality "256kbs and above" look at these.

Then there are the Premium options that most of these offer for a Monthly fee or $4.99 and up or Yearly fee of $49.99 and up.
I wont list the illegal options as downloading off YouTube is on the same path but if your wanting to steal then don't complain about the quality.
