The bio on their website says they plan to release 7 singles from the album, so I'm wondering if there's 2 more tracks coming? I do find it odd they put lonely path after Insidious on the EP release. Can't imagine why.
In the age of streaming the model makes more sense to release monthly to keep feeding the algorithms, eventually culminating in a full album. A YouTube guitarist i follow, Bernth, started doing this. He broke down the math in one of his videos to compare what happened after he started treating spotify like YouTube.
