For my long-time favorite artists (been following 10-20 years), I go with CDs. I enjoy hearing their albums as a whole. Otherwise, I go with downloads so I don't have to commit to the expense of a whole album. These songs are more "disposeable" to me and if I lose them through system crashes (I do back up) or unsupported DRM (such as the March 31st end for Sony Connect songs) I won't feel such a great loss.
I've been buying CDs for nearly 25 years and while my collection numbers in the thousands, at least half of it is crap that I was forced to buy in order to get the one or two songs I really wanted. So, how to keep the concept alive and well? Better overall albums with little filler crap.
What type of music do you prefer whether it be CDs, Vinyl, Downloads subcribtion, or even radio? And if you prefer physical media then what do you think is a good idea to keep the concept alive and well?
