Unable to change song details...

So I purchased the song "Work B**ch" by Britney Spears, and upon hearing that the album will be called "Britney Jean," I went to change the album name to "Britney Jean" from "Work B**ch - Single." After syncing my phone to iTunes, the song still appears under "Work B**ch - Single," even though the album title says "Britney Jean" on iTunes. I've un-checked and synced, then re-checked and synced - no luck. I've deleted the song and re-added it both from the computer and from my iPhone 5 - no luck. iTunes Match is always off for me, and I've never had this problem before. Any suggestions?
