It makes sense to do lots of low budget videos instead of wasting all your money on one massive production.
The video for Hardwired is great and took them 9 takes and was on line two days later.
They did Moth Into Flame and Dream No More in the same day.
I don't know how much the video for " The Day That Never Comes " cost but i'll bet it was a lot.
For my bro to do a video like Moth Into Flame - he would charge about £5,000 at the most.
If Metallica spend *roughly* $5,000 a video that's $60,000 for all the songs on the album.
If each of those videos gets hundreds of thousands of youtube views they might even recoup it instead of one video that cost like $100,000.
