MP3 files can be created at different bit rates.  Perhaps you should 
take some sample
audio files and create some MP3 versions at different rates and see 
whether you can
actually tell that even the high bit rate MP3s are less accurate than 
original files.

If you can tell, then fine, keep the huge detailed files.  But if in 
fact you cannot
tell, sacrifice a bit of quality.


I have some original recordings made in the last year or two at choral 
concerts - mostly
24 bit, 44.1 khz, stereo uncompressed WAV files, made with ecent quality 
condenser mics.
I was surprised how hard it was to tell the originals apart from eg 
320kbps MP3 let alone
eg 160kbps.  And I was listening extremely carefully, criticising my own 
recordings.

I came to the conclusion that what one might call blurring of the 
details of the sound,
caused by the acoustic of the concert venue and audience noise, already 
hid detail even in
the original files, and the consequent blurring of compression as MP3 
didn't take away as
much detail as I'd expected.

(I'm 57; I expect my hearing is no longer what it used to be.)
