Music - Choices?

I want to incorporate a certain amount of music into my video to run over the clips when there isnt any dialogue.
Or in one scene where my character has all the work infront of him along with a laptop and facebook. I want him to have a song on his iTunes playing loudly, preferably a dance or youthful track.


Some songs I have thought about are:


White Blank Page - Mumford and Sons 
Possibly could be played all the way through the clip or when my character has piles of work a possible white blank page could relate to the lyrics in the song.
Black and Blue - Miike Snow
 I think this song would be an ideal choice when the credits are on and the clip is coming to an end. It would also work as an entrance to my clip.
I Just Called to Say I love you - Stevie Wonder
Perfect choice for any shot involving a mother and son
We Can Work It Out - Stevie Wonder
A positive song, another possible choice for the closing credits when the title of the film is raised.
Alors en Danse - Stromae
This dance track is a catchy outgoing song certainly reflecting youth and what my character intends on being.
Come Together - The Beatles
A Beatles classic will be recognisable by all ages of the audience also could flow nicely through all clips. The literal meaning of the come together lyrics perhaps suggesting a bonding and development could work well along the basic trailer story.
Me and Mandy - Example
A weekend song with links to going out with friends and family life. Another possible choice to have on the laptop/computer scene.
