Sorry, my bad. UNIQ returns indices, not values. So it's even simpler:

idx = [-1,uniq( yourarray[1,*] )]
value = fltarr( n_elements(idx)-1 )

for i=0,n_elements(idx)-2 do begin

void = min(abs( yourarray[0, idx[i]+1:idx[i+1]] + 42. ), min_index )

value[i] = yourarray[0, idx[i]+1+min_index ]

end

However, note that this only works if the track numbers are sorted!
I'd stick to Matthew's approach, which is more generic!
