For specific video extracts of the music from the Inauguration go to the Papal Music Youtube site.
For those who missed last Sunday's programme For the God Who Sings on Australia's ABC Classic FM, including roughly half of the music on the new Westminster Cathedral Choir CD Miserere, you can listen to the programme again by clicking here - a great opportunity to "try before you buy"! Available for another 25 days as at writing.
I've also just noticed that this week's programme (for broadcast on 24 March 2013 at 10.30 pm) has another track from Miserere - the Guerrero Ave Virgo Sanctissima.
