I loved Debut when I was younger, but I don't like it as much now. Post thru Vespertine is actually my fav bundle of albums too.
As far as Medulla, I like that song "Where Is The Line" with Rahzell.
Pagan Poetry is in my top 10, along with Headphones, Joga, the Next To Last Song (from the movie), I can't think of it but it's on Homogenic...
I used to have her remix album (Telegraph I think?) And the string mix of Hyperballad is awesome. I also had the Family Tree remix set.. some good stuff on there too.
