Condolences to you and family.
Both of those songs are great contemporary songs. I am sure she was singing it while you played them.
I learned from a reliable old preacher with many signs and wonders that the soul can stay up to 40 days on earth. We experienced this with my mom's passing back in 99. It was a bit strange with my mom's spirit hanging around us. Everyone felt her presence and strange things would happen around the house. So, if she chooses to, the man upstairs can allow that. I know that you guys are sad but make no mistake, her spirit lives on and you guys will be reunited some day.
God Bless
