I'm not sure he needs any "music-related credibility" (whatever that is) to make valid points about Ping. I'm pretty sure all he needs to make valid criticisms of Ping is:

1. iTunes (check) 2. the desire to use a music-oriented social network (http://www.last.fm/user/swizec - check, I think)

The only thing I can think of that might disqualify him from having, uh, cred here is that he already has a last.fm - I bet Ping catches on best, if it remains as it is now, with people who haven't sought out a music/social network, but see Ping in their iTunes, hassle-free, and decide it's pretty neat.
