How to fix my SIMS FREEPLAY for iPhone?

I have the newest update for the Sims Freeplay game for iphone4, (the Halloween update) and my goal is to add a new sim.
At the moment, I have 15 sims, not enough money to pay for a new sim, (costs $250, 000) and not enough life points to get one that way. (costs 10+ life points.)
I also can't buy a crib, because I don't have a married couple, and they can't get married because I don't have the life points to buy a ring!
So I'm trapped in this circle, and don't know what to do!

Please, any suggestions will be very much appreciated: D

How to make iPhone 5 shuffle more randomly?

I've created a playlist in iTunes with 3 artists, artist A has 150 songs, and artist B and C have 150 between them, so i'm expecting to have artist A on more of the time, but so far I've listened to 23 songs, I've had 2 songs from artist B, 2 from artist C, and 19 from artist A!

It's not just this playlist that it happens, it seems to pick an artist and play that artist a lot more commonly than other artists even when i'm playing my entire music library, (5k+ songs)

Does anyone know a way around this? I need to change it on my iPhone rather than iTunes, as i very rarely actually listen to music off iTunes.
