I know what you mean man, when I finally started putting tunes out under the name of Crypticz I just wanted to keep all my sounds dark. I still make dark tunes and have some new dark stuff coming but I have just started expanding my sound! I made a more uplifting Future Garage thing the other day and also have made some more Tribal stuff and also trying my hand at Grime. Now I just say I make Bass Music cause I can fit lots of styles into that
Basically, what I am saying is is don't restrict yourself! Just make whatever comes out dude
As long as it fits under one big main genre I don't see a problem! Your sound will always be changing
Take Skream as an example. Started off proper dubsteppy with like The Judgement and Request line and now he has tunes like Where You Should Be. Those are completely different style tunes and all his fans seem happy !
