Your song choice must include a true BPM change of at least 10 beats per minute.

- This may be in the form of one single BPM change or multiple BPM changes, as long as the BPM range includes a difference of at least 10 (e.g. 125-152).
- The BPM may return to the original speed.
- Dividing or multiplying a song's BPM by a power of 2 does not count as a true BPM change.
- However, as long as the song does include a true BPM change, doing this is not prohibited.
- If your song's true BPM change is less than 10 BPM, dividing or multiplying the new BPM by a power of 2 cannot be used to circumvent that.
- For a BPM change to count, there must be notes in the chart (not just already held Freezes/holds) during the section with the new speed.
- For example, if your song changes from 152 BPM to 125 BPM, there must be notes during both the 152 BPM part and the 125 BPM part.
- Be sure that this BPM change is at least +10 or -10 from the other charted BPM.
- Live BPM/drifty songs do not count. It has to be an intentional BPM change.
- The BPM changes as indicated in some rhythm games don't necessarily count. For example, beatmania IIDX doesn't have a stop function, so it temporarily uses very slow BPMs and then compensates for that as a replacement. Therefore, some songs' BPMs will be listed as slowing to a very low number like 3, when the song actually has a constant BPM.
