Tried listening to one of my unreleased songs on my car radio and phone, and had to go back and fix more things. Needed a little low-passing to avoid "boom" on bassy setups...and I spent an hour trying to track down and fix some background crackle/hiss that was driving me nuts. Turns out, the one time I used a drum loop instead of making my own from one-shots, there was some background noise that got brought up from compression. >_< (Ended up throwing a denoising VST on it and calling it a day.) Silly analogue drums and their not being TR-909s...
