I have been doing music for 3 years now, and I have a LOT of unreleased music that I used to feel like they're unworthy so I didn't upload. Even the last four songs I uploaded were created quite some time ago..
Since I felt they aren't too bad anymore... I am releasing them all in quite a fast pace.. maybe 4-5x a week until I run out then proceed on to the normal 1 song a month. I hope that explains why I upload so frequently.
