Great introduction to Persian at the beginning level as well as to more advanced levels. It offers a variety of different lessons that slowly demonstrate spelling, pronunciation, and many other things.
An amazing philosophical poem by Persian poet (philosopher, mathematician, astronomer, any many other titles) Omar Khayyam, written in English and Persian in the above link.
This is a radio website that streams live radio broadcasts of Persian music. I can't understand a thing but it's fun to try to listen for familiar words. The website itself is in English so you can read music updates. There is also an interview section where you can listen to interviews of Persian bands and singers.
