3.Imperativa's rhythm is slower than the last one, but it is quite imposing.
4. Time-popular classics, not much to say.
5. What a dream needs [remix] A magnificent song composed by requiem for a dream.
The above are some beautiful background music I have carefully collected, all of which are classics, but whether it is suitable for your video background music depends on you.
