3) "Which soundclips to remove"
This question only included responses from those who believe that some sounds should be removed, therefore the answers were very limited (only 7 respondents out of 100). Overall, this leads to the fact that no sounds hit high numbers. In the criteria/reasons for removal, "Its addition feels forced" was the most prominent reason as to why a sound should be removed.
Pretty much the same conclusion can be drawn here: Retain sounds, be more picky about new ones.
