Separation of "alternate versions" section on song entries

[andreoda]

Currently, the alternate versions list on song entries displays the songs in the order of the release date. However, on entries featuring popular songs, the list can get very long and confusing. Especially when trying to find alternate versions of songs created by the original producer.
To solve this issue, the alternative versions list could be separated into multiple sections.

Idea:
2 sections:

• alternate versions by original producer (original producer is involved)
• alternate versions by other producer (original producer is not involved)

I do not know yet how these sections could be named.

Example of song entries with a lot of alternate versions + made by the original producer:
