Thanks for all the tips. I was able to save a BIAB song as a Wav file and then use Audacity to convert it to an MP3. I added the audio file to my Android tablet and then used Bluetooth to connect the tablet to my Pyle mixer.

The song played but the audio quality was horrible. Nothing like it is when I play the song right from BIAB. What can I do to make that audio file sound like the BIAB file?
