If you buy music by the Beatles for example, and you first bought it years ago on 45, then bought it as part of an album on LP, then bought it on 8- track, and to keep up with the times, you bought it on cassette and later on CD. You have paid for the artist's intellectual property rights five times and the money ends up with the artist who was already paid for his/her intellectual property rights way back when you bought the 45. Why isn't there a system in place which would allow you to turn in the LP and receive intellectual property credit when you purchase the 8-track, and the same for the 8-track when you bought the cassette, etc. Seems like this would be more fair to the consumer.
