My observations:
To me, the photos are more important (or videos), as J Mac mentioned.
If you walk in my front door, you will see large framed prints of my Grandma and Grandpa's wedding, then them at their 50th anniversary. I also have the large prints of my parents wedding.
Music -- don't know, wasn't there, don't care -- Grandma and Grandpa might have though...
As to the video for DJs, I can't stress that enough. And I don't mean the VLogs (those are for our consumption). If a customer can watch you intro a bridal party, do some traditional wedding/party stuff, etc., then you can book them without all kinds of meetings, and time wasters.
Simple enough to do -- grab a Flip or other camcorder, put it pointing at you, and let her rip. Edit it to a nice promo, and you've got gold in your hands
Clients are not looking to see pics/videos of full dance floors -- they want to know what you look like, your mannerisms, your vocals, etc. You could be the best DJ in the world, but if you do not fit their needs/looks/mannerisms/voice, yer either not gonna get the gig, or you will disappoint them...
Unless you are a multi-op, you are selling yourself -- not a packed dance floor. The only people that care if the dance floor is always packed -- are DJs.
I wish I had had the internet, and all the technology available today, when I was in my heyday -- I'd milk it for all it was worth...
