It helps the site, so I guess it's worth it.

I wonder if all the ATRL+ money is actually being invested on the servers.

So only [ytmusic] tags and size/font?

i only bought mine cos i had the money at the time and wanted to check it out lmao. so far i haven't used any of the perks of it so i probably won't resubscribe when it runs out

I would like to win it in some contest though.

What more could you have expected?
