I think the problem with music broadcasts (TV or radio) is that they&#x27;d need permission of the artists and&#x2F;or publishers before they could sell it commercially. It&#x27;s probably for similar reasons that they don&#x27;t show all the Glastonbury stuff (mixed in with revenue sharing - some artists&#x2F;publishers might want too much, for example):<p>&gt; &quot;On occasion an act may not wish to be filmed or recorded. Artists may also agree to be recorded but only allow a limited number of songs to be aired. This could be for a number of reasons for instance: the quality of some parts of the performance, because they do not wish to broadcast new or unreleased material, or they do not want to broadcast their entire live set.&quot;<p>I do agree that it&#x27;d be a good idea to do, though.
