Disney Sing It: Party Hits follows the same basic layout as previous games in the series. As the song plays in the background, lyrics appear on screen along with a glowing ball telling you when to sing certain words. Additionally, there's a pitch meter set along a multi-level track indicating whether to go high or low with each word. It is a fairly simple premise to follow, and even if you don't get it the first time, it won't take long to figure out what you're doing.
One unique option allows you to play songs in either Normal or Karaoke Mode. When flipped to Karaoke, the actual singer's voice is lowered, allowing your voice to carry through the speakers. It's a small option, but one that separates the "real" singers from those singing backup.
Even if you can't sing, the scoring system is overly generous. You aren't guaranteed 5-stars every time, but even if you screw up and miss a line or two, you can easily win back points. Once the song is finished, you can replay it in Encore. This is another fun option that adds replay value and lets you alter your voice through various filters.
Sing It: Party Hits comes with one microphone as a pack-in. Another mic is required for multiplayer and not every mic lying around the house will work. I attempted to play with two other microphones and the only one the game would detect were Logitech ones. Similar to Family Hits, the pack-in mic is a little too "hot" and picks up every noise, though it never interfered with gameplay.
For what it aims to be, Disney Sing It: Party Hits is a good game. It's nothing that will appeal to a wide audience, but it isn't really trying too either.
