My Friends is Upset She's Not a Bridesmaid

Tough. I'd simply say something about how you appreciate her as a friend but at the end of the day you had to make a very hard decision to only include a few of the friends because of budgets. You're trying to make her feel included by letting her sing. Maybe tell her she can help plan the shower/bachelorette party if she'd like to be included in that (as long as the others don't mind). The only thing she'd be really missing out on is having to buy a dress and stand by you for 30 minutes. At the end of the day, it's your day and not hers. I understand not wanting to lose her as a friend, but she needs to get over herself. Maybe even the MOH needs to tell her to chill out a little. You can't please everyone.

I would just let it go. You knew this was going to be a tough decision and may hurt them. They will get over it. But if it was me I would also have a back up song to play in case she decided last minute she didn't want to sing anymore out of spite.

Just stop engaging about the issue.

Honestly just let it go. I had a sort of similar issue. I knew from the start that my bridesmaids were going to be my family, my sister, 2 cousins and my sister in law. I had this friend, We've been friends for about 15ish years. As soon as we got engaged she thinks shes going to be in the bridal party. I never even mentioned it to her. Mind you she lives in New York and I live in Pennsylvania. So we don't get to see each other much. So on Instagram my bridal party put up that they're so happy to be in my bridal party. I also post something. She gets super pissed and texts me some BS. Long story short, we're not friends anymore. She still would've been a guest and been involved in other stuff but in my eyes she ruined that for her self. We haven't talked since late September.

Seriously you have so much else to worry about! If she really was your friend she would understand your reasoning! Exactly!!
