>>102269738Seems clear to me. First sentence is very structurally inelegant but still grammatically correct and understandable, provided you're not ESL.
I'll break down his post into parts, which will hopefully help you get his meaning:
>How hard working are they Beginning with a rhetorical question meant to cast doubt on the claim being responded to, which was that they're hard working.
>that they have next to no music on their channel this yearProviding an example to support the previous assertion.
>despite claiming idol is their priority? Explaining why having little music on their channel is relevant for refuting that they're hard working.
>All they have are paid collab songs and one EN cover.Further context being given on the lack of things to show, according to their own explanation of where their effort is going.
