Is it better to sync iphone with itunes or add songs manually?

I've had an iphone for years but I always add my music manually (vs sync with itunes). I never had enough space on my mac to keep all my music so I would delete everything after I added it to my phone. Now I finally have space on my computer…
so should I just add all my music to itunes and set my phone up to sync automatically? Will this make things easier/better in the long run? Losing everything in between isn't a problem because I already have my music backed up to a file on a separate hard drive…

**sorry if this doesn't make sense/rambles and thanks very much in advance for any answers! Much appreciated.

I think, that sync your music automatically will be better, eaiser and faster.

  • Why can't I delete or add songs onto my iPhone through iTunes 11.0.4? I can delete songs directly off of my iPhone but even if they're deleted, iTunes still says they're on my iPhone. I also can't delete any songs off of OR add any songs onto my iPhone through iTunes. What is happening. I have fully updated both my iPhone and iTunes.
  • Songs in itunes won't sync to ipod but will sync to iphone? So i have over a 1000 songs in my itunes library and they will all sync to my iphone no problem. But when i try to sync to my ipad (which has enough memory available) it will not.
  • Need to add new songs to iphone without deleting old songs So my old computer crashed and with that i lost all my music that was downloaded to itunes, so i only have those songs saved to my iphone now i just spent $25 on my computer downloading music, but when i went to download it onto my phone it said it didn't match up with this computer and that in order to sync new songs it would delete my entire music library on my phone! I really don't want to lose all my music but i also want my new songs on my phone!
  • My iphone won't let me manually add music? For some reason everytime i try add music from different itunes it makes me delete everything.i've ticked 'maually add music' but still i have problems… Any idead? I drag the music over and it just won't copy.
