There are many kinds of Angels - some other Angels have also suffered.
The next oldest Angels and most similar to the Borg Angels are known as the
Ministering Angels. These sing beautiful songs of love and compassion or
how they will never leave God's side - they sing amongst other things they
do and they are loved dearly. They are fiercely protective and defensive
about God.

There are a group of band of Angels who are very creative and original - so
much so that all the ideas and creativity and imagination that exists among
humans on Earth in their entire history - would only be less than one
percent of the creativity and imagination and diversity and originality of
these Angels.
The spark of their originality would cause the most awesome reaction on
Earth - so they are kept well hidden as humans have never seen or met anyone
like them!
There are Angels who are so blind with love for God - that they cannot see
nor hear anyone or anything but God. They often walk into walls and do not
even notice!
They love God so much that they cannot even think!
But when Angels sing in harmony - they are wonderful at this - where each of
these blind Angels has a "ooooh" or a "la la la" or an "aaaah" or a "doo be
boo" or a "sha la la" and each one of these Angels has a specific line of
harmony and a specific phrase.
