Frequency compression can be useful to avoid dead regions in the cochlea for speech, but this does not follow for music. The difference is that in damaged regions—typically in the higher frequencies—speech has a “continuous” spectrum, whereas music is always a “discrete” or “line” spectrum regardless of frequency.

The Speech Intelligibility Index (or SII) shows some interesting characteristics. The difference between 340 Hz and 3,400 Hz (coincidentally the bandwidth of the telephone) is fairly similar for continuous discourse, whereas there is a high frequency bias for nonsense syllables. That is, whenever there is a context to speech, there is a greater reliance on lower frequency sounds.
