Mp3s are compressed, and the CD audio is not. If you make the mp3 at a reasonable bitrate (save the jpeg as high quality) it is almost indistinguishable from the CD audio(the TIFF).

TIFF is a lossless file...JPG is a lossy file. Using your music analogy:
Altering and saving a TIFF file is like recording a CD from a CD. No matter how many times you do it.
Altering and saving a JPG is like recording a cassette tape from a CD. And the next time you alter and/or save, it's from the cassette version. And the next time, it's from
that cassette, and so on, and so on...a little more quality loss each time.
It's a sort of extreme example, and not really too noticeable at first, but the more a JPG is altered and/or saved, the more loss of quality there is. For that reason alone is why I archive my images in a lossless format, usually in original raw file.
