Its a strange one for me this is, as I tend to only listen once, to something that is streamed, even if I like it I don't generally go back to it, I think its because of time restraints. There is so much music available these days that it is hard to make a choice as to what to spend the hard earned cash on.
I brought a CD at the weekend after listening to clips a couple of months ago prior to the pending release date, this is in my opinion the way it has always been with me, although the promotion is slightly different in todays market place, that promotion comes before the album is available and that promotion tended to be the "single 45 vinyl or single CD". Although that in itself was sometimes not considered, because if you were a fan of a particular group, artist, etc. you brought their latest release without question.
In days gone by everyman and his dog taped the chart show from the radio on their trusty cassette player, I even used to record tracks direct off the TV from forward thinking shows like "The Tube" or "Rock goes to College" here in the UK. This is no different to ripping stuff from You Tube, SoundCloud, Bandcamp whathaveyou. In my opinion its not down to if the whole of the music is available or just a few clips, its not even about supporting a particular band, artist etc. its about if you really want to own that product, to be able to do whatever you want with it and listen to it on various devices in its "best quality".
Obtaining the music in its best quality is the only way to get the most rewarding experience from it, this goes for music of any genre and as such any music that is available to hear via an internet stream should never the best quality available, if your happy to listen to music in substandard quality then that's your bonus, you will always be able to get free music and nobody on this planet will be able to stop that happening. There are too many people fretting about HOW we get music these days instead of remembering why we used to buy it, why we had to have that latest released gatefold sleeve LP with all the info, the pleasure we used to get from putting it on the player and hearing most of the tracks on it for the first time and then not taking it off again until we knew all the tracks on it like the backs of our hands. The physical product in all its glory, and in its best quality, will always win over a downloaded PC file as far as I am concerned.
