Why can't I drag and drop songs from Music to my iPhone

iTunes used to be a, rather odd, but workable system to keep me from selecting the music i wanted to listen to on my iPhone. Yet ever since Apple decided in its " infinite wisdom " ( ahum ) to change this, I can no longer just Drag any Album over to my iPhone.

The only options are to use the Apple Syncing method via Music which in short sucks b*lls big time and is absolutely useless.

The other option is to ( again ) buy all my music from Apple.... seriously Apple ??

I have music you have never hear about...

Third option is to buy ( here we go again with the friggin' buying ) a third party app that will allow me to transfer MY files and MY music to MY iPhone from MY Mac. don't forget Mr. Apple that I have paid for all these devices and the music that I keep on them, so you are violating my privacy and my human rights to use my documents ( music ) the way I want to.

So in short, I have nothing to say about my music anymore according to Apple ??

WTF Apple !?!

I am very very angry about the removal of this Drag-And-Drop option that was always there but now suddenly has be taken away from the users without offering any other option ( not counting the useless option of synchronizing ) .

Does ANYONE have a solution or should I start calling Apple about this ??

Thanks
