Startup Idea : Lyrics Auto Remix App

Takes popular songs, intelligently indexes the full lyrics noting the proper parts of language (e.g. nouns, verbs, adjectives, etc...) as well as syllables counts and any rhyming patterns. User can pick a song, select a theme for the remix nouns (e.g. Body Parts) and a them for the remix verbs (e.g. Urban dictionary) and the song will be automatically rewritten with proper syllable count and rhyming. Or could be made so that it's easy for someone to write in their own words. Makes for fun karaoke sessions. Could build community board around each song and see who has the funniest and best performance of a remix. Possibly great content generator for YouTubers.
