def leppard's hysteria released 7 songs. love bites, hysteria, pour some sugar, armageon it, woman, rocket, and animal. well 6 were big hits!

as far as Bon Jovi goes it is hard in this time for them to release that many songs. the radio only played 2 songs off of crush and bon jovi did release 4!

Misunderstood was the second single and did better than the first single.

Bounce was released to rock radio and was the third single.

i think that the fourth single "all About lovin you" will make a big impact and will help them sell more albums. its one of their best ballads since Always!

There is no way that there will be a fifth single. unless they sell 5 million copies in the next few weeks.

hope i helped.
