No problem with Irish, US or Austraian songs - just go to Quick Links at the top of this page, click on ST Keyword search, and browse away. Or wait for the suggestions to come to this thread.

Indian songs are a bit trickier - but here's a page that links to a whole lot of Indian songs, with written and sung lyrics in various Indian languages - and also with English transations.

The Indian lyrics won't show up properly unless you've got your browser tooled up to show them, but the English translations should impress your teacher, especially if you can copy the sound file.
