i tryed to adding more songs but if i put to much songs they dont play
Welcome @Ismael_Luna! 
First, sorry for your trouble. I tried doubling the number of tracks that the widget comes with (total 22) in an attempt to duplicate your issue but had none. If you know, do they stop playing after after a certain number of songs, or after a certain time period (e.g.., after 20 songs or after 30 minutes of playtime)? Also, what media format are the recording you are adding (MP3, MP4a, .oga, .wma)?
Hi there, @Ismael_Luna 
Apologies for the delayed response!
The Audio Player widget lets you upload up to 1000 tracks. The maximum size of 1 file is 100MB.
If the number of tracks uploaded in your widget/ maximum file size don’t exceed the current limits, please try to upload those tracks once again. I’ll be happy to investigate it for you
