It’s hard sometimes to find a really good mashup that blends two (or more) songs together. Via Shahar Varshal on YouTube, this video contains 5 different pieces blended into a fun mix:
From Elvis Presley, we have Bossa Nova Baby.
From The Red Hot Chili Peppers, we have Dani California.
From Queen we have We Will Rock You.
From Flo-Rida, we have Whistle.
From Cee Lo Green, we have Crazy.
