An album for me as a teenager in the '70s was a fully formed concept. It was a body of work from an artist I liked or trusted or who excited me. Maybe one of the songs is really poppy and you listen to it on the radio as a hit single and then more of the world is about to find out about this artist by buying the record.
I think that I have a pretty varied taste in music I think. And it is primarily rock music big umbrella that I am, I am not into hip-hop. But, I do like both.
