Yeah , but the same argument applies to FAT, NFS , UFS and all the
others
too , no ?

Well the audiofs from http://fly.cc.fer.hr/~ptolomei/audiofs/
uses the page-cache with no problems.

Alltough after using it for 5 minutes I don't think it makes sense,
because it won't give any speedup ( unles you have vast amounts of
memory, the beginning of the song will be flushed when you try to
read it again and also all the other usefull cached data, just the
end of the song will be in the cache , but it will be flushed as you
read the song from the beginning. It would only be good for small local
accesses, but that is not a tipical use for CDDA. The only benefit is
maybe
the read-ahead ) and just uses up the cache-memory from better usage.
