Still at a loss, but....
I found the most amazing site. Oddly enough, I found out about it from my good friend's marketing class syllabus, which was doing a case study on the company. The site is www.hitsongscience.com. There are other sites out there that predict what you will like based on your tastes, but this takes it a step further. Using similar technology, the company takes a song you submit and analyzes it for each of it's musical components against the chart hits over the past 30 years. It then gives you a score based on the likelihood that your song can be a hit. Now, obviously it doesn't take into account everything, such as lyrics or the amount of money spent to promote a song. However, the analysis of the math aspect alone of the song's musical structures makes it intriguing. Hope you enjoy it......I am going to submit a song soon and see what it scores!
