I note that almost all of the albums reviewed on this site can be listened to in full by visiting the 'Bandcamp' link at the end of each review. I have the 'Bandcamp Psych Rock' page bookmarked and search the "New Arrivals" section every few weeks. This allows me to sample every new album without relying on a 'reviewer' to present their pick of new stuff.
I'm not saying that TimeMachine doesn't do a great job of presenting and reviewing new psych music but like you say they have a prog/psych bias and obviously can't review every new release.
Here is a link to the 'Psych Rock' section of 'Bandcamp'. Scroll down and click on 'New Arrivals' to change from the highlighted 'Best Selling' tab.
