JoeViola,
Just my two cents, but asking how to spread your music is a lot like asking how artists spread their paintings, or poets spread their poetry. What advice would you give them? Go to where people are paying for music: high school bands, film and tv producers, be creative!
Here in Orlando, we have an outdoor shopping mall called Disney Springs where musicians are paid by Disney to perform covers of seasonal or trendy music, and so they build an audience pretty quickly. Imagine if all those musician's new fans went to his site and found his original compositions? What a great way to introduce people to your music.
How about the composer who transcribes music for recent films and sells them to middle-school bands who want to play selection from Moana, or whatever other movie kids like. His fans (school band directors) will definitely stumble upon his originals, as well.
Understand that people generally don't search very hard for new music. If you want them to hear what you've written, you might have to bait them into listening with something they DO want (covers/soundtrack transcriptions).
Good luck. :-)
