Unreasonably Vague Requests Eureka 7, Trinity Blood, and Bleach

first is Eureka 7 Episode 28 "Memento Meori" It’s the song that is played throughout the entire episode. Ray says it’s Charles’ favorite song. It has a lone haunting vocal hook, which at the end is integrated into, an extremely catchy, albeit, somewhat normal, trance beat. ***I know that there is the song "Get it by Your Hands" which is supposed to be Charles’ favorite song, However, this song lacks the vocal line that apperas during the episode, and I’m looking for what that vocal hook is from, eh?***

Next would be Trinity Blood Episode 9 "Overcount 1: The Bellfry of Downfall"
Ok, so I don’t actually remember anything about this song. It was probably slow, and played at different points during the episode. gomen nasai… I can’t really remember anything about it, aside from the fact that it was in that episode, and I really dug it.

Finally, Bleach Episode 9 "Unbeatable Enemy" Once again, I remember nothing but I really liked this song when I heard it at various points during this particular episode. It was probably played when Ichigo was having flashbacks, and during important emotional declerations he made but that’s just a conjecture based on Anime norms… I have no idea what it sounded like.

if there are multiple versions of any of these songs, it’d be cool to know. Arigato.
