I am sure it requires work. I havent played with it a great deal other to find users. Tags should work but that is a guess.

That is a good idea to have a search within the tags. That would drill things down even further.

2/ Then one can go into the tag and so like a subsearch using another keyword.

Then it is simply a matter of getting the second word as the tag used.

Make sure to tag the title, artist, album and genre if you really want to make it easy as possible to find.

I wonder if that could be built into a community if threads is incorporated at that level. Like a template that one fills in. Then the data is there and the search is easier.

Things to consider.

I don't see why not. Most Youtube downloaders can scrape all the info through the url of the vid, so it could definitely be done and even autofill the info for us.

Right, I nor most others will simply scroll through vids someone else shared until we find something we like.

No that is true. Most will not. The tag is messy. The only way is if someone sets up their own container with stuff they like and maybe share with their friends.

Search is vital. 1st test: see how long what is there stays indexed.
