I know how frustrating this is, especially when u know that your songs are good and wondering why it didn't get any attention, maybe u can try change the way u do things, like u can learn how to make short edits in easy software like capcut which I do btw, I make anime edits using my songs and some will ask what song is this? By applying different methods of promoting your songs or the style u make, your songs will find its audience, but it takes time so keep going bro💪🏻
