Village People founder Victor Willis -- the cop in the group -- tells TMZ ... he just loves the fact his band's iconic earworm has seeped into the political arena this election cycle -- even if that means it was heavily kickstarted by Donald Trump at rallies.

In case you hadn't noticed, Trump was big into incorporating "Y.M.C.A." as a go-to tune during his final blitz across the country -- often dancing to it on stage, which actually got made into a 2-minute long compilation clip in sync with the song. So, yeah ... it's been revived.

Of course, on Saturday ... the song was sorta hijacked by Biden supporters in Philly who danced to it while trolling Trump supporters from across the street (who were actually playing it) ... this as Joe Biden was announced as the projected winner of the 2020 election.

On that front, Victor tells us that's A-OK too ... everyone's invited to sing it. So long as the track continues to get play -- not to mention climb back up on the charts, which it's also doing for the first time in literally decades -- he's good with anybody getting down to "Y.M.C.A.'

As we told you, Victor had already signaled it was cool for DT to use the track -- and he reiterated that here with us as well ... saying he had no plans to sue Trump or his campaign.

If anything, it sounds like Victor is grateful to Trump for resurrecting not just "Y.M.C.A" ... but also "Macho Man," another Village People classic. Alec Baldwin even sang a rendition of it on 'SNL' this weekend, so it's all Village People all the time, it seems, these days.

To Victor, that just speaks to the universality of his music -- and the message of overcoming obstacles that apply to just about any and everybody who's going through adversity.
