So you could translate "die Genres Religious und nischenmusik" as the religious and niche-market genres.

Problem: niche market music can often sell in the thousands (ie: new age, early classical, Indian classical, heavy metal, baroque & renaissance classical), but expensive distribution network and physical costs make traditional CD pressings expensive and a very risky investment.
Solution: aggressively pursue personal contacts, especially for well regarded, niche-genre artists. There are many good artists in these genres, recording costs are low, but poor distribution network and high costs limits artist's possibilities, increase their frustration.

Here in the U.S., the style sells more than Latin pop, rock, and tropical acts combined. It’s one
of few genres that haven’t suffered significantly in the music industry’s recent downturn. Yet despite ts massive U.S. appeal, Mexican regional remains ghettoized within the music industry as an “ethnic” niche-market genre whose domestic audience is never expected to reach beyond immigrant communities in the West and Southwest. The music receives little promotional backing from record labels and garners the fewest licensing and sponsorship deals of all Latin genres, despite the fact that it outsells them all. Its standing in the Latin music community is so low that Mexican regional artists boycotted the inaugural Latin Grammys in 2000 to protest their vast under-representation in the show’s award categories.
