: The problem here is that you didn't leave any edit summary or note on the talk page, nor did you cite any sources, so I had no idea where you got your information from. This creates a problem - we can't change content simply because one editor asserts it is "inaccurate", it must be sourced. For example, you said "BBC Radio 1 simulcast live a discrete stereo audio mix, synchronised with the TV pictures of the concert", but this source says "It was not a live simulcast as previously thought, as it was not broadcast live on Radio 1." You can't both be right! This is why it's important to cite your sources, so other people can check that what you say is factually accurate. Have a look at Referencing for Beginners to see more about how to cite sources, and why it's important.
