I don't think anyone big will release a new single these days, am i right?
What a strange thing to say? We live in a world where young artists like Adele and Ed Sheehan can still come along with big hits that dominate the charts for months. There will always be a threat that some new or hot young artist will come along with a massive single that captures the public imagination in exactly the same way Mariah did with OSD.
We've already seen in this thread how close several artists have done it. Its very much a plausible reality.
