Positives:
- Graphically better (although that is of secondary importance at a karaoke game and generally is subjective)
- Cool songs on the Blue Ray (of course subjective)
- Option to avoid failure in microphone on your smartphone
- Playlist by smartphone possible
Negatives:
- Frequent crashes (I was previously on the PS4 not even)
- SingStar "Ultimate Party" has ironically not party mode. Only 1-2 players possible.
- The starting time too long
- No different degrees of difficulty
- Start takes over a minute
- In game very slowly
- Huge drawback: most of the songs purchased for the PS3 is not available.
- Poor communication / "crisis management": No statement as to whether or when the songs will be available.
