While I'm not a huge fan of the falsetto, in some cases I think it works. As PM says - it certainly works for me in songs like WW and OOTN. It also works for me in Fast Company to give it some of its 'funkiness'. For me, the use of the funky falsetto is particularly effective here in delivering the message so it does not come across as being too preachy. To be more specific about TBF's question, it's not that I don't like Fast Company because I do. It's just that there are so many other songs on the album that I like better.
