Well using some BSB original songs, they've already got quite a few relevant ones, maybe a few lyric changes:
I'll Never Break Your Heart - I'll Never Burn Your Heart
Get Down - Fall Down
Quit Playing Games With My Heart - Quit Playing Games With Moriarty
Anywhere for You - Where the Hell Are You?
Everybody (Backstreet's Back) - There's a Body (Adler's Back)
Shape of My Heart - Burn of My Heart

Also, please note that sentences can also end in full stops. The exclamation mark can be overused.

Mycroft’s popularity doesn’t surprise me at all. He is, after all, incredibly beautiful, clever and well-dressed. And beautiful. Did I mention that?
--Mark Gatiss
