Hello!
I would liek to prepare some song which is modern and pretty hard to sing.

Jazz/popular/any, just modern!

Can U reccomand me anything?
Many thanks in advance!!!

Hello Lemon1,

You haven't stated your gender -

If you're looking for female vocals I would recommend Rhianna's "Only Girl in the World", it requires a lot of strength and control.

If you're male, I have a student working on Miguel's "Use Me" and it's a very worthy challenge.
