+ "One is that the original analysis is very sensitive to how the sentiment of lyrics is determined. That means I'm not too confident about the reliability of results from either fitteR-happieR or this notebook.\n",
+ "\n",
+ "Another is that the Beatles are undoubtedly better than Radiohead. The happiest Beatles sonds are happier than anything Radiohead have done, and their saddest songs are about as sad as Radiohead. In just about every measure, the Beatles' range of music is larger, and covers, Radiohead's.\n",
