Thank you for your answer.
Crossfading would be also very fine, for to use cog as player at parties. wma I don't need that much, since I only have a few wma-files and toast converts them to flac, what I prefer.

Like Bootsy said: "May the groove be with you"

Even though I believe other users would have wished this already -

Crossfading
Gain
Limiter/Expander
Support for the different wma-subtypes without drm

Thank you.
