SID. They've done so many emotional anime songs for me and the main singers voice is honestly P E R F E C T the way he sounds when singing I've never put my finger on it if it makes me sad or pumped it does both to me honestly. They're definitely in my top 3 for J-rock bands because of how calm his voice it yet I feel there are so many connotations behind the way he sings here are a few songs of theirs I've listened to a lot of their songs more than this but these are the main ones that got me to look them up. The main singer as I said is just BRILLIANT and I honestly think they're my top J-rock band because of how emotional their songs make me feel but along with that they give me motivation at the same time.
I've only heard their opening and closing for FMA:B and their opening for Magi (which I didn't realize was them until I saw this! Cool!), and I definitely love those songs. Time to listen to the others you posted~
