I have to go with Mumford & Sons' album "Sigh No More". To me it's the perfect album. It strikes the right balance between melancholy and optimism. It's awesome folk rock, the harmonies are epic, Marcus' lead vocals are outstanding, the drums can be like a freight train driving through the album. To me it's one of the ultimate road albums, yet can be just as appreciated sitting in your room. They also incorporate the banjo without it sounding corny. There are songs on the album which just cause me goosebumps every time, which no other bands outside of the Metal genre have been able to do. It's easily my favorite album of the last couple of years. In fact I would place it in my top 3 albums of all time.
