At the moment there isn't enough of next Monday's schedule to tell, but it does look like Trace Urban could be adding more general chart music slots as well, both Trace Latina and Starz close at 7am, and from that point the Trace Urban listings seem to be named more generally and mention 'chart topping hits' rather than 'hottest urban tunes' in the descriptions after 7am. Though I could be wrong since it's too early to tell.
As more of the schedule becomes available, this does actually appear to be the case (although having said that, some of the listings that are there at the moment have got quite general titles, such as "Please Don't Stop The Music", so we'll have to wait and see).
The following are now in the schedule for next week (which aren't there this week):
Top 20 Sounds of the UK 2019
Chart Topping Fresh Hits
What's Poppin? Fresh New Beats
Top 10: Back In The Days
Blinding Lights Hits
Also, a lot of programme descriptions just say "Trace", where they previously normally said "Trace Urban"
The Trace Urban schedule so far for next week also doesn't seem to include the non-music programming, which makes sense given the addition of Trace Latina programming.
