I'm probably going to make some enemies with this, but I am wholeheartedly against the singing of "Don't Stop Believing" at karaoke nights.
My karaoke-loving manfriend says the key is picking the songs you loved when you were 13.
Stop being the curmudgeon who just claps along begrudgingly! Go forth and confidently claim your tone-deaf spotlight!
I was never the best singer, but I reckon I enjoyed it more than Christina Aguilera torturing a national anthem, and that was all that mattered.
