These kirtans are stored in both poscript and .dvi formats. They were generated with TeX using the musictex and devnag packages.
The postscript and Acrobat versions don't look great on my screen, but your milage may vary. They should (I hope) look good if you print them using a 300+ dpi printer. The Acrobat version is generated with a resolution of 1200 dpi which should be adequate for most situations
As an alternative you may want to try instead the *.dvi versions. This works well if your web-browser knows how to start up a suitable TeX previewer.
