How to listen to music without itunes?

Question

iPhone

Like many newcomers to the Tech, iTunes is mostly frustrating. Especially frustrating is the inability to download music normally from multiple devices (2 PCs and network storage).
Does anyone have experience using one of the following methods?:
1 Upload music with some kind of iTunes analogue, which will not delete files from the device without finding them in its library
2 Player, which will be able to create playlists from files on the device (jailbreak installed )
The best thing I've found so far is Bridge from Sidia, which seems to be supposed to add mp3s on the device to the Music library.

Answer 1

We install any third-party MP3 player (buy in the AppStore or w3bsit3-dns.com for example), and fill the folders with music in its file sandbox through the same iTunes, iFunBox etc.

Answer 2

jailbreak

Answer 3

You can try to put the manual music control mode on the device, turn off synchronization and fill it with your hands. I live like this, norms, although I upload muzlo from one device.
