i don't know if anyone asked already, but how about adding a fullscreen visualization feature? watching dizzy-making colours while listening to online streams should be extreme fun! _____ By the way, thank you for your great work!
You can do it yourselves. Make animated gif the size of the psp screen, save it on MS and bookmark the link, then you can open it when listening. Gifs will however take lots of memory, so for gif big as a screen you will most definitely run out of memory
Sorry mate that's not possible because radio don't broadcast lyrics. Most stations broadcast RDS` though. (`Radio Data Service) 
Although in an very short time the radio will crash.
