In modern times I don't really have many go to songs, just depends what I'm playing around with. I'd have to go through what I test with the most and make a list, even to just rethink of old tracks I grew up using, might be cool, maybe I will at some point, IDK. To add some past and present.
Some off the top of my head from when I was younger:
69 Boyz 199Qaud album got a lot of play testing subwoofers.
So So Def Bass All Stars Vol.1.
Hi Town DJ's We Came To Groove
Dynamix II Color Beats album
Then a mix of tracks, stuff like:
Master P Never Ending Game
Break Em Off Something
Bourbans and Lacs
other No Limit albums
Down South Hustlers Bouncin and Swingin compilation had some good tracks with bass
Bass Thugs Drop Your Bass album that had some good tracks too.
Lot of stuff I'm forgetting right now, maybe I'll put together a big list of tracks one day I use to test with, along with some of the modern stuff with low bass I use.
Kind of depends on box tuning / subs I'm playing with. Some of that older stuff thrived with higher tuned ported, or sealed boxes and do not perform as well high lower tuned and or higher Xmax setups. Example of more modern track, I have a lower tuned box with a pair of 10's in my truck, and Young Dolph - Coordinate rebassed track really gets things moving:
Or
Young Dolph - By Mistake
Birdman Filthy Money
C-BO Die Broke
Also Bass Patrol Twenty 15's been a fairly steady go to track
