LevelThePlayingField: Last song at Regional Convention of 2016 was stolen from Audiomachine
thank you for researching this
The use of stock media - photographs, graphics, video and music - is very common, and known about - it makes sense for many companies and organisations as it's often the quickest and cheapest method of getting the required results.
Stock music for movie trailers (yes, even big budget movies) is an interesting - and not so well known by the public - niche genre of the stock media industry - and I believe that it is this that the WT used for the video in the OP.
Take a look at the closing credits on the JW Monthly Broadcasts - you will often see stock media being credited.
Anyway, that's all known about and is nothing new....
BUT - having done your research - how do you know the WT stole the music? As you clearly state in the topic title?
You've researched it - so you are not 'making-it-up' - you are making an informed statement that the WT stole the music on a public forum.
So thank you, that's interesting, please tell us more! - what research have you been able to do that backs you up?
