Hello Ian, I would also like to thank you for releasing XMPlay 4: thanks!
I've been a user for over 10 years but I've been silent, as per the saying "if it ain't broke, don't complain it".
Before discovering XMPlay I was a Winamp user. I loved Winamp 2. As for Winamp 5, not so much.
There is much to praise about XMPlay. It is small and efficient, yet highly capable and backward compatible. Without the MIDI soundfonts it weighs in at under 1 MB of disk space. XMPlay is humiliating all other music players that weigh more and do less. Including Winamp.
Finally, thanks for making available the default skin from XMPlay 3: I am not a big fan of the flat skin of version 4. Maybe someone could make it less flat by using shadows and gradients? Sorry not me, because I still haven't graduated from MS Paint.
