DJ Max Trilogy: Music Videos?

[Pop'n Chevo]

Apologies if this has been asked/answered elsewhere, but I have a question. How exactly do you unlock the music videos? I've played the game a lot, admittedly usually on 4k mode, but I've only unlocked one of the music videos. if i know how to get them it'll give me something else to do while I level up to get the remaining songs.

Thanks for any help.

to unlock a MV, clear the song in 4, 5 and 6k in every difficulty level
so if you want unlock a music video you'll need to play 5 and 6K as well (but no need to play 7 and 8k)
