## Submission Format

There are 51630 test examples. The submission file will be a CSV file with two columns: `dataid` and `prediction`. `dataid` is a unique identifier (between 1 and 51630) for each song, and `prediction` is the estimated released year for that song.

For example, if you predict songs 1 through 5 as released in the year 2000 and rest of the songs 6 through 51630 as released in the year 1900 the submission file must look as follows

```
dataid,prediction
1,2000
2,2000
3,2000
4,2000
5,2000
6,1900
7,1900
8,1900
9,1900
10,1900
11,1900
...
51629,1900
51630,1900
