Folk music at its finest pressed to 3 instead of 2 CDs

Looking for a Kastelruther Spatzen CD for my mother, I came across these 3 CD box set on Amazon. The price-performance ratio is very good. The title from the years 1992 to 2009 show a broad cross-section of the music group from South Tyrol. It is quasi folk music at its best, for those who's like ;-) The sound quality of the CD's is very good, the box 3 to create visually beautiful. However, when you consider that there are on each CD, only 14 songs, and the CDs have maturities of approximately 48, 50 and 46 minutes, then you can legitimately ask the question, why the title is not on an otherwise mostly conventional 2er double CD Box has pressed? If you like the music of the Kastelruther Spatzen, makes this 3 CD box intended nothing wrong and gets good folk music at an affordable price.
