Running me up the walls

[ManExposed]

So, Last night I pulled up Chain of Flowers on my PS3's youtube channel so I could listen to it while I was drawing.  Then I saw in related videos a song name I had never heard before.  Up until now, I thought I had all of Cure's songs... But that one song led me to find about 20 more I had never heard of and it's driving me crazy.  They're on youtube, but I can't find better qualities of them online anywhere it seems.

Some of these songs I've listed so far are

A Boy I Never Knew
Ariel
Truth Goodness and Beauty
everything forever
Just say Yes
You are so happy (you could kill me)
Everything forever
Heavy world
a sign from god
just say yes
100 seconds
This Morning
Yesterday's Gone
Sluvy
Fake
Strum
Please come home
Esten

Anyone have a collection of these rarities and perhaps others I've never heard of that I could perhaps have?   I came here feeling that the people here would know more about the Cure's discography than I do.
