IDEA: Playlist processor

Create a website that accepts uploads of a music playlist and provides:

• A list of songs I like. Basically just a very friendly listing of the songs contained within my playlist
  
• An analysis of the type of music I like to listen to (kinda of like what WTF Music Info does)
• Suggestions of music that may appeal to me

How to be profitable:

• Use an affiliate link to songs and music I may like
• Advertising to key music websites

What it needs to be successful:

• Access to a very large song database (like CDDB) for comparing and extracting information from a song list
