Hey man pretty cool. I listened to "Like a Spider". I'll go back and grab some more when I get the chance.
The first thing that I noticed was that the piano sounds great. It's a nice full tone...really nice, but I noticed it was mostly in my left ear. I would have liked to hear a more stereo image, but that's just a personal preference. It sounds great, and that's the most important thing.
The second thing I noticed was that there was some noise on the vocal track (which overall sounds great. She's a hell of singer). I think you could have solved the problem by either throwing up a gate to cut out the noise, or if you are recording with software, trim the wav down and eliminate the noise. The noise I'm talking about is kind of in-between words (for example: at 00:18-20 between the words "spider & spins"). It's not going to kill the song by any means, it's a pretty nitpicky thing.
Other than those very small things, the tune sounds great. Excellent job, I'll download some more!
