Simple audio player

Finally moving away from windows (again) after selling my MBP last year.

One thing i love with windows is winamp,Allowing me to dump a load of files on the desktop and create a simple playlist with winamp.Are there any simple audio players like winamp for the mac.

If not,One thing that bugs me about itunes is ,say i dump a folder of tunes from a memory stick into the library and then remove the stick ,Itunes cant no longer find the files.Is there a way of say copying a folder across which is located on the desktop and it automatically adding the files to the library, which i have located on a seperate HD?

So no matter what i do with the original files the audio has been added to the library?

Many thanks
