just search for files in *.wav format on the internet. Another simple way is to use "Programs-Accessories-Entertainment-Recorder" under WINDOWS. First, open your favorite songs with the player, then click "File-New" on the Recorder, and then click the "Record" button at the bottom of the Recorder interface. After recording, just save it. The music recorded in this way is exactly one-minute WAV music, which is very suitable for starting music. In this way, you can set any song you like as boot music.
