Agreed the source material probably makes quite a difference. I'd  
imagine there's music that would be transparent at ~100 kbps while  
other might require ~160.

As previously stated I do believe the AxelF sample is in the  
harder-to-encode region for MP3 encoders so I'm pretty sure my  
concentrated listening threshold for average music is somewhere around  
130-140 kbps or so.
