MP3 files, are compressed. It's an old solution, to a problem of transfering files over the internet, and eventually used
in personal music players. Because a compressed file takes up less space in memory. But when you listen to them, they
need to be "uncompressed" just before you hear them, and they lose some data in the process. Mostly in the low end
and mid ranges. Flac files are a form of "uncompressed" files from start to finish. Thus the term "lossless". They don't
lose any data. Better to keep the flac files, and only use MP3's for personal music players.
I can't come down, it's plain to see.
I can't come down, I've been set free.
Who you are, and what you do,
don't make no difference to me.
