Recover iTunes Library
I deleted my iTunes library yesterday, and want to get it back in its entirety (exactly how I had it with my artwork changes, adding lyrics, etc.) -- I have been using Time Machine for a year now, and used my last Time Machine backup to restore my iTunes. After restoring the library, none of the tracks were able to play. Exclamation points are next to every song, and a pop-up occurs saying that "The song '(insert track name here)' could not be used because the original file could not be found. Would you like to locate it?" I click "locate", but it just takes me to the original song folders, and doesn't do anything.
Long story short, all my music IS there -- but I do not know how to play it, or where to exactly find it. I have gone to iTunes -> Preferences -> Advanced settings, and changed the location and all that (several times), but I STILL can't get any of my music to play... please help!
MacBook Pro, OS X Yosemite (10.10.5)
