I was a bit worried that the alien music would be drastically different from Earth music and with it being too loud I can see how Ianto passed out. That must've hurt the ears and the brain. Ouch!
Author's Response: Yep, Ianto had a headache now and needs lots of pampering and good painkillers. A lot of alien music is probably quite pleasant, you just have to be careful whose alien iPod you get hold of... Thank you!
