An improvement to the original Parappa the Rapper in every possible way! The music, the characters, the gameplay, everything about Um Jammer Lammy is so clean and fantastic! I also think the nature of the presentation is a lot better, having Lammy basically play a Jazz game imitating the lyrics with her guitar. And the fact that there's an entire hidden "Parappa mode" for nearly the entire soundtrack just makes it all even better!

Seriously, if you love Parappa the Rapper but never got around to playing this, you're doing yourself a huge disservice. This heavily overshadowed installment deserves so much more recognition.
