UKNY and all others still fighting with iTunes, looking for alternatives and worrying about your libraries.. there are 2 important things, esp. those with concerns over iTunes deleting your songs - that you can 'bullet-proof' yourself by doing.
First! ..and this is the big one - make a new folder at the root level - so when you open a Finder window to look at your hard drive, you will have 5 folders - Applications, Library, System, Users and 'My Music'. (the folder can be named whatever you want - I use "Musicmp3s" for my songs) With iTunes OFF, go into your Home/Music/iTunes/iTunes Media folder and Select All and drag-and-drop your entire library to that new root-level folder you made.
When iTunes throws a wobbler (and now with all the internetted online clouded stuff it is being made to do, 'wobblers' are more common than ever) 99.999% of the time, it will blow up in your face and take out files in the default location. Simply moving the library to a different folder, for whatever reason, changes the preferences *just* enough that it stops that rubbish from happening.
When you restart iTunes, go right away into the preferences and to the 'General' pane - rename your library to the name of the folder you put at the root level of the drive. Then go to the 'Advanced' pane and change the iTunes Media folder to the new location. Make sure you un-check the 'Keep iTunes Media folder organized' ticky-box - any songs you import whether from your own CD collections or via the Music Store will be put in correctly anyhow. One less way for iTunes to move, sort, catalog or otherwise mess with your songs - YOUR FILES - is always to be encouraged.
Now, once you have all your music moved (and at this point, if you haven't backed up all your songs, now would be a good time to do it) and the new settings in the preferences pointing at that new library location and you've un-checked the organization ticky-box, it's time to do the purge of the iTunes library list.
Empty the Trash on your computer. If you miss a song, it's simple then to rescue it once the final flush of iTunes is done - mind you, you shoudln't need to, but you never know when a file will try and give you the slip.
Once all is set, simply go to your main library window (in song or list view is best) and Select All and clear the list to delete. It will ask you if you want to move the songs to the trash (on those with pre-Yosemite systems, simply moving your songs out of your User/Music folder wolud be a Move - in the later OSes, it's a Copy, so the library will still be at it's default location.. have iTunes move it to the Trash. That you emptied the Trash before means that you can double-check the contents and see if you missed anything easily. You should now have a totally empty iTunes with all your songs tucked safely away on both a backup, and in that root-level folder you made.
To rebuild that Library from the new location, simply go to that root-level folder, and drag-and-drop it into the empty iTunes. It will take a while to rebuild the library and it does two things - analyzes the songs for the gapless playback and looks for the album art. I have FOUR libraries - and have for the last 6 months been slowly merging all my libraries together and have out of 40k songs, only a couple hundred that are from the Music Store - and have, for the last 16 years been occasionally rebuilding the library to 'freshen' it up, when it starts to slow iTunes.
Make rebuilding your music library a every-few-years event, it allows you to get a handle on your files so YOU own them, not iTunes or Apple. (In an early interview with Walt Mossberg, who is the technology writer at the Wall Street Journal, Steve Jobs stated well over a decade ago, that he did not think it necessary that a user control their files - that the applications would do it *for* them - so the instances where an app goes sideways and deletes people's files.. oh well.. right? Ehhhh.. I don't think so.)
The other SECOND great thing about using a non-default location for your songs, is that you can easily change up the music player you use and have it not get into any issues with it interfering with or accessing the iTunes folder that maintains all the playlists and preferences.
So in getting back to you, UKNY, YES! I use many alternative music players - Nightingale (http://getnightingale.com/) my go-to when iTunes gets a broken update, and if your unsure of apps from outside the AppStore environment, there is Vox (http://coppertino.com/vox/mac) - which I have dabbled with and works nicely and also the wonderful open-source Clementine (https://www.clementine-player.org/) - actually, there are tons of different music players, if you are willing to dive into it, and many can sync iThings as well as iTunes and have streaming radio sources beyond Apple Music's services.
Good luck!
