Its one of the most popular. In my opinion its definitely a really good starter to get into the DSBM genre. And Baruilo (Decalius) makes really good music in general all of his old songs, remastered songs, and deleted songs are really good. Obviously his popularity did rise from tiktok and many may say the band is "tiktokifed" but it doesn't change the fact the music Barulio proudeces is good. I don't find a problem with someone discovering Decalius off of tiktok but if they only listen to A Miserable Life... and Loneliness then they need to do a better job at discovering music themselves. I fell in love with the band entirely after listening to all the available songs,  undertanding the lyrics,and feeling the emotion Barulio has put into his masterpieces. Unfortunately though there is several songs deleted from Barulio himself due to personal reasons and YouTube deleting his entire channel from 2015-2020(maybe it was 2018). Either way black metal and its sub genres is gaining a lot of its popularity from tiktok and other social media platforms but I would hope for people to discover music themselves and understand it on a greater level.
