Ooh, lots! Here's a few:

-the sound of Blaze "clicking" across the floor (lol!)
-Blaze's bark and dog tags (me too)
-the sound of horses galloping across fields
-the whinny of a horse
-the sound of rain pattering gently on the windows
-the sound of my dad laughing (really, I love his laugh so much!)
-and just hearing my good friends talk to me on the phone, since I don't see them often!

I'm sure I have lots more, but that's all I can think of for now!
