All-American Rejects - When the World Comes Down
Fall Out Boy - Folie a Deux
Both are really enjoyable. I highly recommend them. If you're downloading select songs, I recommend:
Fall Out Boy - "Disloyal Order of Water Buffaloes", "The (Shipped) Gold Standard", and "What a Catch Donnie"
All-American Rejects - "I Wanna", "Another Heart Calls", and "Believe"
