heres the thing in relation to record sales though.

u2 have had a good few more years to sell records than jovi as they have been active for a good few more years.

bon jovi have probably sold about 128 million or something (incude lost highway sales, thats just a guess by the way but surely its at least 5 mill!)

plus jon will defintely have sold about 15 mill if you include his solo projects.

so say roughly 150 mill sold worldwide which is actually a margin more than U2 is it not?
