Why can't i delete playlists from my iphone?

So all of my music got wiped when i synced my phone to my laptop so i went about rebuying it and afterwords there were about 5 new playlists on my phone and it's not letting me delete them. How can i fix this?

Music that is bought from iTunes music app can't be deleted manually you would have to plugin your iPhone to iTunes then delete them from the music section using your PC.

Except iTunes, you can also use Syncios Free iPhone manager to delete playlists. In this way, you will not encounter the problem of losing songs or other information when you sync your iPhone with iTunes.

  • Why do playlists on my Iphone keep messing up? I have an Iphone 5, there are some playlists in which I try to rearrenge a song, and after I save the changes, the song moved to a different position. This appears to happen on AAC songs that I converted from itunes, I did this because Itunes suddenly stopped allowing me to change the name of artists or songs. Any idea of why this is happening? Is there effectively a relation between the AAC songs and the bugged/corrupted playlists?
  • Why can I no longer drag playlists made in my itunes to my iphone? I used to be able to plug my phone in then just drag my playlists into the phone. I've always kept the phone settings on manual so I can manage the music myself. Now, since I've updated to the newer version of iTunes, I can't drag the playlists over, or the individual songs within it. It's driving me insane
