A lot of the traditional academic applications of the term "kitsch" no longer apply because of post-modernism, the no-brow movement, etc.
Kitsch is often used these days to describe things that are perceived to be "beneath" the abilities of an artist, such as
"The album's serious mood is broken by the inclusion of a kitschy disco number..." etc.
But - if we're talking about how the term was used originally - it would mean the opposite, such as attempting, say, a serious, extended work that may (or may not) be beyond the abilities of an artist.
Again, the old definitions are pretty much out the window these days.
