It should probably be stipulated that although LoFaM is tied to Homestuck via thematic inspiration, it shouldn't be confused with official Homestuck music. The LoFaM albums are very much unofficial, and very much made by fans for fans. So it's less a new Homestuck album, and more a new collection of Homestuck fanmusic, I guess?

You’ve said it better than I ever could. Yes, the LOFAM albums are fan-created works and quite unofficial, not directly affiliated with the comic in any way.

Of course, the silver lining bonus is, because they’re unofficial, they’re completely free (go get the fan albums here!)
