As the title thingy says, It the entire theme song in elvish.

got bored, went to my local common to elvish translator site, worked this out:

Ci'm ei valys
Palia Val ( Palia Val - Palia Valys)....
Ol Palia Thaelyl, ci shar ber 14
Shael cor vasael sher ei baesia mali taloli
air shar paerondraer sai born ei shys ialael
(ni'm kylae tar 'aes eir ter ci'm Palia Valys)
Shael air por's ceri shys, cor thyr, si ber cer
sher sael Palia syl ei jhyl ailodi os air
Saesi shar ei kaer shol thar, aelaeseirol shar talaer
cor tylaelelaer kyr eir vi-eisalaer (Raelais)
Shael ci thos shyji iar, ci vaelojaer
Ci car myrn-shori cas eil kyrdol-kael aer
Ci tyr shar syl shar, poradaes, eil thia!
Ci shar tes tysi ialozia sal si oraes ker
Air shar sael sar ci caern shar ci car sai pai,
ci car sai myr eir si kyr sar shaesi tystol syl
Ci'm caesi sai thol thys ti eil o!
Ci'm kylae tar 'aes eir ter ci'm Palia Valys
Kylae tar 'aes eir ter ci'm Palia Valys
Kylae tar 'aes eir ter ci'm -- Palia Valys!
