Seems a little bright on my headphones (referencing ziggy stardust). Really like the intro aahs. Sounds like a great mix.
Oh. It took me a minute to find the new mix. It's lined in the OP.
Maybe it's not vocal pops, on a second listen. 0:38 in the instrumental break after the first line.
It may also not even really be sibilance. It could just be a tad much brightness emphasizing the Ss.
Or both of those issues could just be low-quality SC compression!
(Which is why no matter how much people complain about it, I'm gonna keep posting my songs as both mp3 and Flac )
Listening to the 3rd mix. There's still a pop at 0:38, so that's probably not Soundcloud. Might want to check your source tracks for those to see where they come from.
Still a little siblance in the lead vocal, but nothing else I can pick on.
This is pretty great. I think the acoustic guitar is at a good level its subtle but it adds a lot. Has a pretty professional sound overall if you ask me.
