And finally, the regeneration is a significant enough event that it should have had its own original piece of music accompanying it. I'm not saying they should have gone over the top and try to outdo Vale Decem, but something new should have been done. Even Eccleston's regeneration scene had a new and exclusive piece of music done for it. Instead we get a tune which was so clearly written for The Rings of Akhaten.
Here I disagree. The centerpiece music of Akhaten "The long Song" and the follow up without lyrics "infinite Potential" was clearly written to foreshadow his regeneration and many people would have been disappointed if he regenerates to some other piece.
Even the lyrics back then screamed regeneration:
"rest now, my warrior, your hardships are over. Lay down. Wake up and let the cloak of life cling to your bones.' Slightly paraphrasing here.
