Problem
Beatmap filename is too long and can't be uploaded to osu.RC
Metadata that exceeds the field's limits (81 characters) must be shortened. Start by dropping additional markers and if this still is not sufficient, indicate that the title has been shortened using ... in a sensible place.If the artist or title fields were shortened to fit in field limits, the omitted information must be added to the tags.
If a mapset track was contributed to by multiple artists, they may be listed with commas inbetween. If there are 3 or more contributing artists and they are not part of one officially labelled group, Various Artists or other descriptive artist labels may be used instead.

Discussion
Point 1: should this title be shorten? it doesn't exceed the 81 chars stated in RC.Point 2: should artist be shorten? it is only 2 so Various Artists shouldn't apply.
Point 3: isn't it better to change file naming convention or increase the limit on filename?
Solution
Personally I believe a code change is better to solve this problem rather than shorten the title. related git issue: https://github.com/ppy/osu-stable-issues/issues/780Solution 1: Increase filename limit
Solution 2: Shorten file naming convention
