Got this idea after someone mentioned Aichan hummed Konayuki in one of those radio shows a few weeks ago.. so my pick would be to hear:
-Aichan singing Konayuki by Remioromen, a very2 beautiful song, and i think would suit her voice really well..
-Aichan again, singing a very sad english song. maybe Everybody Hurts with a lot of emotion (like when the Corrs did it). that would be awesome! but highly unlikely i think
-Morning Musume singing a song from SPEED, maybe White Love. they'd sound great with the melody, maybe like a choir group or something in some parts of the song where everyone sings together in different tunes
so which song would you like to hear your favourite h!p girl/s sing?
