Hmmmmmm, huh?!?!?, sorry but old dog here (woof,woof) and not crazy about the new tricks. While I applaud that they are thinking outside the box and doing modern tech stuff, I wouldn't play this to convert my friends to Libera. I don't want the distractions from the beautiful harmonies that I love and they would be confuzzled by the mixed genres. It could appeal to new, younger fans.
At Sea- nice to appeal to the disco aficionados and can be re-branded as CWA (Choristers With Attitude)but I'm not sure if I like the song better. Freddie M. sang beautifully in it but fun fact- it took me a third listen before realizing the song was in English. I've always have a hard time understanding lyrics sung so I might have thought it was in pig Latin or an underwater SpongeBob dialect. The reverb makes it harder to hear it correctly.
Be Still My Soul- not by cup of tea esp. when I have to keep checking if someone slipped a Mickey into the cup. Tooooo slow which makes me feel drugged.
O Beata- a hipster version with reverb and nice beat. I like this one the best.
Carol of the Bells-this one is OK since it's a fast song so the frenetic additions aren't so distracting.
Angel Gabriel- kinda jumpy with visions of the Chipmunks singing. Now I'm complaining it's too fast

but a great disco beat.
Sorry to be such a purist but I don't want to be dragged kicking and screaming into the 21st century.
