i wouldnt make the mistake of comparing future sales of metallica with u2's, since st. anger hasnt done much good for metallica when HTDAAB has the potential to be the biggest selling album U2's ever made.
10 years from now, i predict each metallica album will be selling around 1-1.5 million worldwide, metallica will be making their nostalgia tours, while U2 will still be selling at least 6-7 million with their each album.
this also affects the overall sales directly, since the new fans will also purchase items from the back catalog. this effect will work in U2's favor.
also, i think one thing that made metallica the band it is was hammett's guitar solos. metal solos dont sell well in todays world, since all other 80s metal bands, even nu-metal bands like limp bizkit and korn has perished and metallica isnt exactly hot stuff any more, i doubt metallica is going to be remember as the biggest band in the world, say 20 years later. they might end up as the biggest selling metal act, although they unlikely due to AC/DC being a way better band, but not the biggest rock band.
also, lets compare where metallica is compared to U2 in their 8th (right?) album. 8th U2 album was zooropa, a very experimental record by the time's standards, and it still sold a respectable 7 million worldwide. now metallica with all their 'die-hard' fans, sold around 4.5 million, with the record they called 'our best record'.
so, with metal a dead genre around the world, metallica doesnt have such a bright future, unless they give up metal and re-position themselves as an RnB/hiphop act with hetfield doing break-dance, bass player doing the rap parts, hammett doing usher-esque vocals and ulrich making dance beats. now that would be a sight.
i think it is pretty obvious that U2 has had an impact on the world culture metallica could ever dream of having. also, a band that sues their fans is not going to be remembered fondly years from now, if they are to be remembered at all.
o yüzden bence bırak bu nafile ugrasları, kabullen metallica'nın zamanının gectigini, ve HTDAABın keyfini cıkar!
