auto delete playlist ?

i'm not actually a playlist person
so i want each time the playlist to be cleared
for example, i choose a band from a folder on my drive, select all the songs of the band and play it with cog
then i want to listen to another band
so i select all the songs of the second band
and here when the songs are being transferred to cog, i want the old playlist (band 1) to be deleted
i don't want to build up a playlist of all songs that i listen (like it happens in itunes)
basically i want it to work like winamp...
play files from my folders but auto clear the playlist when i select other songs then...
is it possible ?
just i don't want it all to add up...
