Now here's for something fun, what's the most forgettable, unremarkable tune you can think of from the last few years? Probably harder than it sounds, because the most forgettable ones are not the ones you remember
I think almost all entries from the past few years have been forgettable, save a few really great ones. When I replied to the 2012 vs 2011 thread, I barely remembered any of the 2011 entries, so I had to look them up on youtube (only to be reminded why I forgot them in the first place).
Most ESC songs are not made to stand the test of time... But if by "unremarkable", you mean "not crap but still impossible to remember", I gladly nominate the Dutch entry from 2011. "Never Alone" was far from awful, but it was so polished and charmless that it left both voters and juries completely cold.
