What was the last successful musical based on an original idea? 'Maddie'?
If you're thinking of the show I think you're thinking of,
Maddie was a clear flop. It only ran for a few weeks. It wasn't original either, being based on the movie
Maxie (1985) which was itself based on the 1973 novel
Marion's Wall.
(Oddly enough, britishtheatreguide.info says in a piece about Lord of the Rings "McKenna & Keeling were the team responsible for the critically acclaimed West End musical
Maddie", while the same site says of
Maddie that it came to an end "after losing a claimed half a million pounds in its short run. Cameron Macintosh blames the critics who, he says, do not understand musicals". So it closed because it was acclaimed by the critics? It's fun when press releases clash.)
I think the main reason there aren't many musicals clearly tied to the present is that by the time you've written and published a musical, persuaded someone to invest in it, found a venue, assembled a production team, hired a cast, launched a publicity campaign, and finally opened, it's not the present any more. The situations are history; the music has been left behind.
Musicals that are too tightly bound to a particular time rapidly become dated. The only way to avoid that is to base the show on a theme that's universal, and then the setting becomes less important. If you want to write something that's tied to a specific time then it's best to use a time in the past. That way you know that the setting and the musical style of the period will still mean something when your show is produced.
Making your show too modern is a huge risk. Suppose, for the sake of example, you want to write a musical about something really contemporary such as MySpace. Two years ago MySpace was unheard of. Two years from now nobody will care about it: it'll be old news, just another Internet fad that ran its course. You get a year or so and a single chance to make a success of your idea, and if you run out of time all your work is wasted. It's hardly surprising that few people make the attempt.
In my opinion anyone interested in improving himself should not rule out becoming pure energy.
