I agree, Matt.
I find the Windows WMA files better to listen to than MP3s.
When I write my songs, I always use the 'Ultrapak' version of BIAB because it is on my computer and this is how BIAB Audiophile version installs the program.
Then, when I want to create a final production, I work with the WAV files on the USB drive.
I can hear a difference between WMA and WAV with most instruments.
Because I'm getting old now, though, my ability to hear top end frequencies is fading, these days the difference between the two file-types is less noticeable than it used to be.
I always upload the Audiophile-derived end result to Soundcloud.
The upload is then automatically compressed to 256kbs AAC (~320 kbs mp3) as high quality streaming format (as far as I understand).
