Wow, I'm very much the same as you.
My favourite albums are also
Natural Beauty and
3 depending on my mood. I honestly just can't choose between them.
'Over the Time' TIME IS OVER is also good, but doesn't seem to hang together quite as well as the other two do. (I love
Flying People though!)
I haven't actually heard
Rainbow *shame*
I've never been able to download it, and for various reasons I've not been able to purchase it either....
As for
ONE LOVE, ONE DAY, ONE LIFE, my copy hasn't arrived yet.
I also discovered COS through Projectj! At the time though, I was really taken with Bonnie Pink (which is how I found the site in the first place), so while I did download the sample of
The Spirit of this Place, I didn't give them a proper listen until a while later.
Then I felt like an idiot for having overlooked them.
My favourite track right now is probably
Purple Sky
OHOH! I'm doing a
COS Wikipage! Check it out and feel free to add any information you can! ^-^
