While researching a topic, a student has taken the following notes:<br/><br/>* The Million Song Dataset (MSD) includes main audio features and descriptive tags for popular songs.<br/>* Audio features include acoustic traits such as loudness and pitch intervals.<br/>* Many algorithms use these audio features to predict a new song's popularity.<br/>* These algorithms may fail to accurately identify main audio features of a song with varying acoustic traits.<br/>* Algorithms based on descriptive tags that describe fixed traits such as genre are more reliable predictors of song popularity.<br/><br/>The student wants to explain a disadvantage of relying on audio features to predict a song's popularity. Which choice most effectively uses relevant information from the notes to accomplish this goal?<br/><br/>* Many popularity-predicting algorithms are based on a song's audio features, such as loudness and pitch intervals.<br/>* Algorithms based on audio features may misidentify the main features of a song with varying acoustic traits, making such algorithms less reliable predictors of popularity than those based on fixed traits.<br/>* Audio features describe acoustic traits such as pitch intervals, which may vary within a song, whereas descriptive tags describe fixed traits such as genre, which are reliable predictors of popularity.<br/><br/>The MSD's descriptive tags are reliable predictors of a song's popularity, as the traits they describe are fixed.
