Like the title says, I was adding some music to my phone, then I noticed later that all but 3 random songs were gone (I think I had 50 total before). Not a big deal as I have them all on my laptop but they're still taking up space and after re-downloading all my songs, I have only 400mb left. I have Win 8 on my laptop as well and neither of the Windows phone apps, nor my phone shows duplicate songs. I have re-booted my phone as well. Any fixes that don't involve me formatting my phone? Any help is appreciated.
