A guide of how to edit the database, @transformer, @anderflox
Part 1. Adding a new channel
1a. Find the /user/ID
E.g. You are listening to
one of Maikel6311's upload. If you click the channel name, you would be linked to the channel ID
https://www.youtube.com/channel/UCL-ltQ ... yZyVz9EeoA
Old channels tend to have their usernames as their channel ID
https://www.youtube.com/user/Maikel6311 (Channels now need 100/200 subs to make custom ID)
Some have a newer/fancier /c/ instead but funcitons the same way as /user/
https://www.youtube.com/c/maikel6311
1b. Search (Ctrl+H)
The ideal one is user ID and /c/, second choice is channel ID. Copy the user ID Maikel6311, switch back to the database tab, press Ctrl+H to search the whole database if the channel is already indexed. Not necessary to double check by searching the channel ID if you found nothing when searching user ID.
1c. Adding to the database
Copy the url and add
/videos at the end like
https://www.youtube.com/user/Maikel6311/videos. Consider there are near 1800 channels in Not Sure and mostly will never be checked, if you find a channel very likely to be a channel, put it under Nigthcore channels -> Pending. Otherwise, all in Not Sure.
Channel name, channel url, sub count, last upload date (active if last upload <3 months), put active and current date in Notes (column H), format 2016/5/16 (should have done this since the beginning)
Part 2. Sorting a channel
First update channel name, channel url, sub count, last upload date (active if last upload <3 months), put active and current date in Notes (column H), format 2016/5/16
2a. Listening trial
Listen to the 10 most recent uploads with Nightcore in title, then mark not nightcore count in notes. I sometimes listen up to few dozens of songs to have a more accurate %, click the actual % for more detailed info (only available for few channels).
Some hardstyle are acceptable if you believe it would be a hands up track if the hardstyle kicks are replaced with hands up kicks. Same applies to house but with extra caution.
To be in Nightcore channels
A channel dedicated to nigthcore (with optional uploads that are not nightcore), 70%/80% uploads are nightcore. A plus if there is genre in title if uploads are not nightcore.
Mixed channels
40%/50 to 70% are nightcore. If it is mixed (and I still have faith), I would also listen to the oldest and most viewed ones to see what they started with and what they are known for. However the most recent uploads are still the main consideration as it is a preview of what subscribers will be getting into.
Pop, Rock, etc
<30%/40% are nightcore, either a channel with 1 or 2 nightcore among 10 other that are not nightcore (the nightcore uploads are usually reuploading old nightcore songs), or uploading pop, rock, etc all the way.
2b. Other info/channels
