I don't remember anyone that used it in years.
I've used WinAMP ever since it began... but it was V3 when things began to go wrong....so have stuck with 2.9x ever since... for 2 reasons...
I skinned for it...and did transparency codings for others who did....
...and because I was referred to as a 'clusterfuck' by its CEO.
Up yours, LLAMA ...if you go belly up it's your own stupidity.
Truth of the matter was/is that a bloke called 'fli7e' almost single handedly invented skinning [of an OS/program] when he reverse engineered WA and 'skun' it.
Thanks to him....and beyond....we were spared the absolute ugly-crap that was the default WA experience....
