Hey, my band is jus starting off and i would like to make songs that are kinda like blink 182 cause almost all of their songs i can relate to and i relly love them... any steps or suggestions for making lyrics or melodies or backing harmony to sound as good as some other great bands

practice, write them alot until you get better at writing them
I have been trying to write songs for bout 3 months now….I still suck but I am much better than I was when I started
