I found that song on cambridge-mt, that site gives multitracks for soundmixing workouts. So there was a really hard case, because this guys have a poor quality records, sometimes clipping, sometimes distortions on vocal lines, and there was a drums issues like incorrect microphone derection, many noises from all mics. And vocal has been recorded with acoustic in the same time, so guitar line has a bit vocal line and vocal line has a bit guiarline and when you need to correct them separatley it makes many issues... and there was a lot of another issues... And as you can see I fixed all record issues and some arrangement issue, but still song isn't ready at my opinion. You can listen other producers on youtube to compare sounding. ;)
