Cream pieces?

In recent years, Josh Groban has released a successful album after another. The question remains why he only so had to make an album? The answer he must give himself. Here he sings songs from all of musicals. All songs are carried by his great voice. However, I do not think that can come close to this album the success of his other albums. To known the songs. Some of these songs have been sung by many artists. I have each of his albums, except for his Christmas album. But I do not think I'll even buy this album. I am not a fan of cover versions, even if you have to say that they are very well presented. Of course, he has also always been covered again on his other albums songs. But an album with cover songs is nothing for me.
