Two videos gave me an idea of what happens when bringing different things together and make them into one product, depending on how you do it. One video (http://www.youtube.com/watch?v=tprMEs-zfQA&playnext_from=TL&videos=m2rgYIVNmH0) taught me a good and well-organized combination makes a harmony. The other (http://www.youtube.com/watch?v=tjY3UvQ2n98&playnext_from=TL&videos=y2i5x5pavdc) was the example of bad arrangement. What they did was simply putting videos together of people singing the same song and playing it at different level of quality, which makes the whole messy. This can be applied to when you want to make your claim convincing and reliable.
