Bittersweet Sampling

Recently I've been getting into old-school hip-hop and modern electronic music that is composed mainly of samples from other pieces of music, movies, and etc... So since my interest was ignited by this entire style of making music, I decide to read up on the history and origins of this whole culture of sampling. While reading, I found out that an entire slew of music I've heard in the past is actually sampled from other pieces music. For example the video I posted above, sound familiar? This song, The Last Time, by The Andrew Oldham Orchestra is a cover version of the Rolling Stone's The Last Time, but many from my generation wouldn't have probably associated it with that song. This song might sound extremely familiar because part of this song is actually sampled in The Verve's Bittersweet Symphony. Now the fact that The Verve's Bittersweet Symphony is not a completely original song does not lessen the value I held and still hold with this song. Bittersweet Symphony is still one the best songs I've heard. This brings to view this whole "culture of remix" we currently live in. Almost everything we listen to, watch, or read borrows from something else. We live in a time where nothing is really authentic, nothing is really 100% original. But does that mean that art nowadays has less artist value? Does that mean we should consider everything that borrows from some other work as a rip-off? On the contrary, since we live in an age with so many forms of art, so many different styles; remixing, borrowing, sampling, and rearranging, makes something we love and hold dear into something new and fresh.
