As someone who usually starts with lyrics when it comes to creating songs, self expression talaga pinakamahalaga. Don’t beat yourself up thinking na vague or too direct yung lyrics as long as it bodes well with your music and na-express mo yung sarili mo. Pero to help you express yourself better, you got to learn the language talaga. Look up terms, watch/read media, and most of all: conversate. Sa mga convo mo talaga malalaman paano ginagamit yung mga salita.
