Big iPhone music problem? IOS 7.0.4 itunes 11.1.4?

Ever since the new iOS update to the 7, the music playlist known as "purchased" on my iPhone no longer shows my music that i just bought from either my computer or my phone. It also doesn't show anything to recently added despite there being like 12 new songs on the music itself. Also, before it used to show very old music purchases that i since deleted and i accidentally pressed the "download" button and they redownloaded because I didn't know what that was for and now I can't delete them. I cleared my purchased playlist on my phone because nothing was in order like it is on my iTunes account on my mac. How do i fix this

Use only one Apple ID for all purchases. If you use two Apple IDs, you can't see the purchases for one while signed in to the other.
