Q: how can i rid U2 song in playlist of my device? ( i already did SOI removal )

Hello Aung Zaw Htun,

Thanks for using Apple Support Communities.

If you have already used the removal tool, and just need to delete a song from your iPhone, simply swipe on the song and tap on Delete.

Delete music and audiobooks

Remove songs, albums, or audiobooks from the Music app by swiping to the left and tapping delete.

 

Delete music, movies, podcasts, and other content from your iPhone, iPad, iPod touch - Apple Support

Take care,

Alex H.
