They would appear to be. I've bought several songs from them. Most have no brand but I've been told they are made by Panorama (makers of THM) They also have some THM, MM and Sunfly.
I don't like that they don't tell you the brands upfront, which is particularly frustrating when there is more than one listing for a song - I'd like to pick and choose when there's a choice.
Also their unbranded Panorama's as well as the THM's tend to have the music and lyrics just a bit out of sync so I've taken to shaving about 3/10 of a second of the front end of most songs.
The unbranded Panorama's have decent music but the lyrics tend to be blue words with a white wipe on a black background so the words I'm about to sing can be difficult to read while the ones I've already sung are easy
especially at a distance, so I've been changing the lyrics to bright yellow with a purple wipe.
Even if you don't like 'em they are cheap way to get those must-have-now songs until your'e regular brand comes out with'em.
