Well, I am not going to argue with you because I don't really care one way or the other, but for the record (no pun intended):
1. the title of the album includes the word "tribute" so one might be inclined to believe that it is a tribute album
2. all songs are performed by one band called Iron Horse
3. I have never heard anyone deny that bluegrass is a form of country music. But believe what you want.
I said a real tribute, what I should have said was a proper tribute. There are an abundance of those type of "tribute" albums like the blue grass one, they are done by a set of studio musicians with little or no thought put into them. You said yourself that only one group did all the songs. The Motley one was carefully crafted and put together by popular and established country acts.
Also you're right I did say that I wouldn't call that bluegrass album a country album, I was talking about big mainstream popular country music. I should have been more clear. I don't see much bluegrass lighting up the charts these days.
