Me too! ;_; Hm, I wonder if I've heard Blue Days - the name sounds familiar but I can't recall a melody. I'll have to hunt it down and give it a particular listen. :)

Yes indeed! My love of Spitz in particular verges on the unhealthy. XD Number one forever in my heart and all that. (If you like Spitz and Suga Shikao and Suneohair you must be a Honey & Clover fan... ;D)

There's an awful lot of links up there, so if you're wondering where to start, a couple suggestions:

Chara: Tsumibukaku aishite yo (both versions), Milk, Swallowtail Butterfly
Tsuji Ayano: definitely get the Ougon no tsuki cover, also Sakura no ki no shita de
Cocco: Amefurashi
UA: Soramimi bakari or the Kasa ga nai cover

Hope you find at least a couple things you like in there. :) There's lots more where it came from, too.
