T1 can play JPEG music that you copy to the reader from your computer. No speaker must use earphones. I created new folder music for JPEGs but don't have to do this. After T1 is disconnected from computer T1 will find JPEGs you added and place in it's music library. Problem is listening to music drains battery faster. N external volume control so it is many steps to adjust volume, skip songs, and stop playing music.
I do not think it will play music from web site or from epub as you asked and if it did it would still have all of it's clunky interface problems.
