For most of the girls, we have the same music in 2 (or even 3) lengths. We have a couple XL Gold that are eligible to compete L6, but don't have a B skill on each event yet. So, I have their music in 1:00, 1:15 (in case they go to L6) and 1:30 (in case they do XL Platinum or L7). Then, all they need is more dance and to substitute in their new passes.
Older Gymmie was XL Gold last year (with a 1:15 time limit). This year, they lowered the time limit to 1:00 and I cut last year's music as well as made a bunch of other ones. I did them all in 1:00 and 1:15 formats and several also in 1:30 format. OG was trying to choose between the music she used for 1 meet last year (Nationals- she had changed her music and ENTIRE FLOOR routine 2 weeks before Nationals) and one other one... but she couldn't figure out what choreography to do with the other one, so she kept her old music.
