Looking for songs to introduce the unit. 1 BAC

I have used it many times. The lyrics might be too simple for  you but Jessie J. brings so much energy into any room!!!

In the next video she is in Candem Town market, London.

Can we use it for the unit...? I mean... are we learning new grammar,  vocabulary...? not really.

'Price tag' hahahaa. But I like it! Surely my 1st ESO students will enjoy it too.
