As someone on the older end of generation Y, I very well remember the days when there were no MP3s and if I wanted to own a song, I'd have to buy the CD.
I'm curious how many of those from the younger end of generation Y buy CDs? Generation Z people (there are a few of them here), feel free to chime in as well.
I stopped buying CD albums about a year ago. I still buy blank CDs to burn music onto. If I want a song, I now download the MP3.
I still have a ton of CDs that I still listen to.
