Good ways to promote music for free?

[JJEA]

Hi! I'm 15 and I've just made an album. I've put it on Soundcloud, iTunes (sent it off), and Spotify (sent it off). I have 50 likes on my Facebook page (mainly friends/friends of friends etc.), but I want to expand and gain a wider audience.

I don't have the money to advertise, I approached a record label and they said the music had to be professional recorded (my quality is good, but not professional). I don't want to spam etc.

Are there any real and simple ways to make people hear about my music? Thanks.

Thankyou for your replies! Does it matter that I don't have any videos to go with it though?
