Harmony is only mentioned when it takes up a significant part of the song.

I've been collecting these for the series but never posted them before.

Quite a few were murdered tonight, just didn't suit their voices

Take me to Church is a recent classic & i really wasn't keen on this version at all!!

Bring me to life is an absolute favourite of mine & nobody was ever gong to come close to Amy Lee's voice!!

Paint it Black is another of my favourire's & was pleasantly surprised by this version!!

It's impossible to please everyone.

I wish some wouldn't expect the band to replicate the recordings with which they are familiar. It shows a lack of understanding of how complicated it is to make some of those original recordings...Like sometimes days or weeks. The band have to do it in one live take with little rehearsal and a lot of other songs.
Vocals are included as the BBC want to attract more people than those just interested in dance.
Whatever the tune, the band has to make it "danceable," an impossible task with some tunes.
I quite like the singers, but they aren't essential from a dance perspective.

Yeah fair point!! I'm just musing really!!
