As far as those string squeeks go there is a program inside of Izotope's Ozone 4 that can take care of that problem. I am sure there are more programs that can take care of that for you, but when it comes to mastering and nit picky little stuff like that Ozone is the way to go. Go to the Izotope website and check out the videos on there, I watched a guy take out squeeks that sounded exactly like what you need to do. As far as the song, I loved it. I thought the "stop's" could use a better tracking and most of the instruments are just a little off in places. Work on tightness but I think that has already been said. Really like the harmonies at the end. Piano is a nice touch. Is that midi or acoustic? Great job guys. Keep it up. You guys can definitly write a song well, you just a little help on performance. Good rule of thumb, when you are recording, and you finish a track, tell yourself you have a better one in you waiting to get out, it will make your tracking take twice as long, but you wont settle for anything less than what you want exactly. You guys are great.
