Axel has written a bunch of catchy tunes over the years, my favorite records are "Nasty Reputation" (featuring Rob Rock on vox), "Between the Walls" (feat. Jeff Scott Soto) and "Masquerade Ball" (feat. Johnny something, I can't remember his name).
The only thing that bothers me is the absence of evolution throughout his career, and now his songwriting has become very predictable (I'm not in a rush to hear the new one...). When you own 2 or 3 ARP albums, it's almost like you know the whole discography.
