get all the CDs of my favorite bands that they had ever producted...

i have a stack of cd’s that’s almost my height but i realised that as time goes by i find more and more artists i like there fore meaning i need to add more cd’s to list and unless i was a millionaire then i couldn’t afford all of these cd’s. in total i would need about 20 stacks of cd’s my height to say i have the full collection..
