I'll try to give আপনি a various list. Sorry it will prob be long and what's sad is that this won't even scratch the surface on the জীবন্ত সঙ্গীত I like, there's just too many haha.
Brothers Conflict opening "Beloved x Survival"
link Code Geass R2 opening 5 "World's End"
link (note: done দ্বারা FLOW and they do a lot of জীবন্ত openings that are good. Recommend looking up the band)
