probably somewhat embarrassing to admit - but I really like some of the new songs, lol.

But I have no idea what they 'really' are - there is this pop song sung by a girl, it usually plays before Lilly Allen's song. (one I do happen to know)

sounds like she is saying
"timba watch kim me loo...
cabbages timbaloo"

lol - what on earth is this is realy life I wonder...?

In the playlist under settings you can see which songs are in which station.
The original artists and song names are written there.
Original truely simlish songs have simlish names.
