Thats one thing I loved about Winamp, all the plugins. Nothing really compares to the visual plugin workshops and the huge selection is awesome. But for simple day 2 day playing of mp3s I've moved onto foobar, I had to tweak a plugin to add ratings to mp3s idtag but its fast and works great.
For android, poweramp is great and works well with bluetooth metadata. Always thought a full screen classic winamp display on android would have been awesome, but they didnt do that as an option.
I remember back on my 60mhz pentium desktop barely able to play high quality mp3s using Winplay3. Ahh the memories.
