Radio Music Test.

Traditional callout has gotten silly expensive and yields questionable results. Declining participation from telephone respondents has forced prices for callout beyond the means of many radio stations. Moreover, telephone samples completely miss consumers who don’t have conventional telephones, under-representing important segments of the population.
Internet-mediated research offers many advantages over traditional research methods.
With stronger participation from consumers responding to your music questions at a time that’s convenient to them with audio from their computer – and not through the phone – you get better information at a better price.
Obviously, survey participants could skew the credibility of the results.
Many online research companies are not paying enough attention to this issue.
Survey data cleaning is an invaluable practice.
