Not sure what you are looking for, but the new Amyl & the Sniffers clocks in at 35 minutes and I can't stop listening to it.
Classics you probably know but just in case: Wire Pink Flag Serge Gainsbourg Histoire De Melody Nelson Ramones S/T
Shad's new album TAO, which came out Friday, is 37 minutes long and I definitely listened to it over a dozen times in the first 48 hours it was out.
For a more under the radar option. Rips One Into the Night by Petite League clocks in at 29 minutes. It's a fun ride.
