first dance song and mother son dance

ok ladies we are alittle untraditional, at least I think we are, when it comes to this wedding. my fh is a rocker, he would kill me if I tried to get him to dance to some pop song. I like rock too so we r trying to find a rock love song for our first dance. nothing too old....so far I came up with 'nothing else matters' by metalica. I can't figure out how to put a you tube video up so u ladies can hear it bc I'm on my cell. so I'm wondering if you ladies have any suggestions.

then while I'm asking about music, my fmil passed away 4 yrs ago from breast cancer, I was wondering what people do for the groom in this case? she was an only child can't ask an aunt no grand ma either.....I thought about a memory sing like tears in heaven by eric Clapton and we dance together bc I loved her and very sad she won't be there too!

thanks in advance ladies for your help & suggestions!!
