I have made a few Urdu-Hindi language covers of (mostly vocaloid) songs. Here you can find the lyrics, as well as some notes on the translation choices, transliteration conventions, etc.
Indic Reclist Generator: This is a simple script that can generate an UTAU reclist in several different Indian languages (mostly done but needs 'crowdfunded' finetuning). The sheer size and complexity of the phonemic inventories involved make it borderline impractical in use, so it is more of a curiosity (unless you're really brave...?)
