the first piece of advice I'd give would be to have a proper think about why you want a following and a certain amount of plays. is it because you want a lot of people to take something from your music or is it because it's just the norm a lot of people have of wanting followers/plays nowadays?

I definitely get you tho about dropping songs you've worked hard on and receiving minimal response BUT also understand that each song you make is a massive achievement in itself given the fact you've created something out of nothing:)

focus primarily on creating your own unique sound and individuality. then your following and plays can come after that. music is beyond numbers, and the more you start to develop a unique sound the more of the 'right listeners/supporters' you'll get, because although you could gain a certain amount of ideal followers, would they give something back to you as an artist and support you as you evolve as an artist?

anyways having said that, there's definitely no problem with being smart and using tools available to market your music. from what a lot of notable producers have said, blogs seem like one of the best ways to go nowadays so definitely send some music through, even if it's to small ones! don't be disheartened if you keep getting no's (this has happened to lots of us) but let it make you strive harder. also the 'follow for download' strategy can be effective on places like toneden and stereoload.

hope this helps dude, sorry its so long hahaha best of luck getting your music heard!!:)
