I was thinkin on that too but there is a problem. For example: Snake bite love was released in march 1998, new tour started in april. Last tour ended on 1 November 1997. So album could be recorded somewhere between November 1997 and February 1998. I wrote some stuff for my collection about albums, and I dont know in this example did they finished album until end of 1997 or early 1998. The year is important to me. I only need date (year) when it was finished, dont need dates of when recording started and how long was, only year when recording was finished, thats all.
