ffmpeg add music to video playing after video

I'm using ffmpeg to create slideshow of images.

I have to add music in the backgroup which will be played to the size of the slideshow (slicing audio if audio length is greater than video or repeating audio if audio length is shorter than video)

This is what my script is

ffmpeg -y \
-loop 1 -i in1.png \
-loop 1 -i in2.png \
-loop 1 -i in3.png \
-loop 1 -i in4.png \
-loop 1 -i in5.png \
-filter_complex \
"[0:v]trim=duration=6,fade=t=in:st=0:d=1,fade=t=out:st=5:d=1,setsar=1:1[v0]; \
 [1:v]trim=duration=6,fade=t=in:st=0:d=1,fade=t=out:st=5:d=1,setsar=1:1[v1]; \
 [2:v]trim=duration=6,fade=t=in:st=0:d=1,fade=t=out:st=5:d=1,setsar=1:1[v2]; \
 [3:v]trim=duration=6,fade=t=in:st=0:d=1,fade=t=out:st=5:d=1,setsar=1:1[v3]; \
 [4:v]trim=duration=6,fade=t=in:st=0:d=1,fade=t=out:st=5:d=1,setsar=1:1[v4]; \
 [v0][v1][v2][v3][v4]concat=n=5:v=1:a=0,setsar=1:1[v]" -i music.mp3 -shortest -map "[v]" -aspect 16:9 -r 24 shortSlideshow1234.mp4;

This generates output, but slideshow is silent and there is no music in the video.

You need to also map the audio:

ffmpeg -y \
-loop 1 -framerate 24 -i in1.png \
-loop 1 -framerate 24 -i in2.png \
-loop 1 -framerate 24 -i in3.png \
-loop 1 -framerate 24 -i in4.png \
-loop 1 -framerate 24 -i in5.png \
-i music.mp3 \
-filter_complex \
"[0:v]trim=duration=6,fade=t=in:st=0:d=1,fade=t=out:st=5:d=1,setsar=1[v0]; \
 [1:v]trim=duration=6,fade=t=in:st=0:d=1,fade=t=out:st=5:d=1,setsar=1[v1]; \
 [2:v]trim=duration=6,fade=t=in:st=0:d=1,fade=t=out:st=5:d=1,setsar=1[v2]; \
 [3:v]trim=duration=6,fade=t=in:st=0:d=1,fade=t=out:st=5:d=1,setsar=1[v3]; \
 [4:v]trim=duration=6,fade=t=in:st=0:d=1,fade=t=out:st=5:d=1,setsar=1[v4]; \
 [v0][v1][v2][v3][v4]concat=n=5:v=1:a=0[v]" -map "[v]" -map 5:a shortSlideshow1234.mp4
