You won't get reported, and if you did nothing would happen. Having different versions of a song on the same board happens all the time. I find it particularly annoying for old video game music where the titles are often general (like "Stage Select", "Stage 1", e.t.c.) and can include a whole lot of totally different tracks all on the same board (there's like 40 different tracks called "Title" by "Tim Follin").
I wish Dylan would try to solve some of these problems. But apparently he's abandoned working on the game (there hasn't been an important update in like three years).
Just report yourself (this will change your score on the board to "2"), find the version most others on the board are playing and do another run with the same tags. Your score will be replaced.
