need songs for wedding video

ok i've been putting this off (as well as pics for our albums) not sure why but maybe b/c once I select these things and they're in my hands it's really all over??

We need 4 songs
so far we have:
Wanna Marry you- Bruno Mars version
Good Life-One Republic

do you think Icould mix in some slower songs? or should I keep the little bit faster paced?

Need some suggestions for 2 more songs please! oh our wedding song was Everything by Michael Buble I have to find out if that will be in there already or not

We have a slow song (better today - anderson coffey), fast song (dirty bit, figured for the dancing part), good life by one republic also. WE just need a third song - I was thinking maybe over the rainbow? Marry you is a good one too.


UGH!

these are what we're using spread out through the video

1. You Are The Best Thing by Ray LaMontagne
2. Raise Your Glass by Pink
3. Good Life by One Republic
4. All In by Lifehouse
5. Marry You by Bruno Mars
6. Knee Deep by Zac Brown Band (this I know will be for the honeymoon pictures)

I Do - Colbie Caillat
Smile - Uncle Kracker
Are You Gonna Kiss Me or Not - Thompson Square

Marry me - train
1234 - plain white tees
Lucky - Jason mraz Colby calliat

We're using Say Hey I Love You by Michal Franti for the trailer

I don't remember all the songs for the long video but I know 2 were You're my Better Half by Keith Urban and Free by Zac Brown Band
