Choosing the right song

Hello! Hi everyone

Here, I really need your help in choosing the right song for my friend. You can hear it here:

His voice cannot stand with high pitch. They are searching for fine song and suitable for his voice.

Thanks

I'd like to see him sing http://www.youtube.com/watch?v=KB6R6eWcm94 or http://www.youtube.com/watch?v=N_u7P75zjf4
