Why do some MP3s sound so bad?

MP3s are artificially reduced files, ie they are compressed. When an MP3 file is created, frequencies that the human ear cannot perceive are omitted. With different data rates, the file size is significantly reduced. MP3 files should have a data rate of at least 192 kbit/s (kilobits per second) so that the quality is acceptable. The higher the data rate, the better the MP3 file sounds, but also the larger the file – if you don’t want to make any compromises and have enough storage space, use 256kbit/s or 320kbit/s.

Amazon tries to achieve an average of 256kbits/s with its MP3 files, Apple mostly sells its songs in M4A format and usually also has a bit rate of 256kbit/s. Since M4A, an MP4 format, is the evolution of MP3, the file is better compressed at the same bitrate. You can’t really answer that on YouTube. It always depends on the quality of the song or video uploaded.
