I've said this before ERB debuted and it basically came true now: management needs to treat ERB's music output differently instead of just doing the same things with her and calling it a day if they expect her music to do well. Not special treatment per say, just different. The easiest way would be to find some up and coming Western lyricist/producer to work with her on coming up with original songs, because her voice and style of singing is so different than the others that just putting out JP music covers wasn't going to cut it. The covers through distrokid somewhat alleviates the issue but it's just really not the same and also she honestly had terrible choices for songs there too so probably her fault there. Before you say cope and say her music wouldn't have done well regardless, ERB is probably the only person ever in holo where her karaoke covers did better views than MVs on her original channel.

None of those clipper channels are very big, and in fact, all four of those clips are the biggest viewed video on their channel. Clearly the demand is there, it's just the supply hasn't and she with the help of management needs to fix that in year 2.
