Need help with video songs!

Sorry!! I know everyone has been postings these..but I can't decide between 2 songs.

We're doing 'Just the Way You Are' by Bruno Mars for Prepartion.

For Formal I'm stuck between: 'I Could Not Ask For More' by Edwin McCain and 'Open Arms' by Journey.

For Highlights I'm stuck between: 'Hanging by a Moment' by Lifehouse and 'All for You' by Sister Hazel.

Any ideas?

Also, would you use a song you knew was played at the wedding (ex: parents' entrance)?

Thanks ladies!
