I thought Boston Pops was Bad;

Stan Getz:
All should be linked under just "Stan Getz"
Stan Getz
Stan Getz / Joao Gilberto featuring Antonio Carlos Jobim
Stan Getz and Joao Gilberto
The New Stan Getz Quartet

Then we have the Duet albums that should link to the individual artists
Stan Getz, Chet Baker
Stan Getz and J.J. Johnson
Stan Getz, Gerry Mulligan

There's others, but those are the only ones to show albums. I didn't see any duplicate listings, but I did see the same album under different group names depending which country it was from.
