New Springsteen odd behaviour


Currently I use iTunes as a database for all my music so that I add albums there, and edit metadata as well.
Today I added Springsteens new Buffalo 2009 concert. Works fine in iTunes, but Roon doesn’t see it at all.
I forced rescans several times, but no luck.

After some research I found that the files are in the iTunes library folder as they’re supposed to, but the album artist is Bruce Springsteen & the E Street Band on this recording.
I exchanged the lower case t with an upper case, as this was how all the other Springsteen albums was tagged, so that album artist reads Bruce Springsteen & The E Street Band.
Then the album turned up in Roon as it should.

My question is how this really matter?
Shouldn’t Roon just read the files as from another artist than the other albums from the “same” artist?
