Lets summarize in point form.
-Your friend told you to send him a song to tell him you like him
-He didn't reciprocate and told you not to do it again
-Instead of asking if he would want to go out with you, you dropped the ball and tried to tell him you just want to be friends and he read too much into it?
-Now you think you can save a friendship with someone you're romantically interested in...
Here is the reality, you like him, so right now you're not friends. You're obviously inexperienced with relationships because when confronted, instead of making the move you ran away. And finally, things are awkward now because he already knows you like him, so now you're just lying to him about wanting to be just friends. Let me punch all this into my calculator over here:
*Beep beep boop bip bip ting ting beep beep whiiiiiirp*
Just as I suspected, you're f*cked. Best bet is to pretend like nothing ever happened and let it blow over. Avoiding him will only make things more awkward.
Your actual best bet is to tell him you want to date him, but I don't think you have anywhere near the courage for that.
