I'll back up Vintage Vinyl. I went there with a friend 4-5 months ago and the place is big. Took a little over an hour to get there but was definitely worth it. You're right, the Metal CD section is huge - best I've seen at any store so far. I was kind of blown away by what they had. Ended up grabbing 5 CD's and could've gotten more but I didn't want to go nuts that day. My friend bought around 10 CD's. I picked up Talisman - S/T, Saxon - Rock The Nations, The newest Manowar, and 2 others I can't remember. They had tons from Thrash/Power/Traditional Metal, Hard/Glam Rock - old and new. They had plenty of titles that are listed on this site. If you can't find something there, there's something wrong with you - nah, just kidding (figure of speech). But really, awesome huge selection and you won't be disappointed so if anyone ever thinks of going - go for it. Music Connection sounds like a cool place to check out.
There's also a record, tape, and CD convention at Merchants Square Mall in Allentown PA that happens every 3 months - so 4 times a year. I went faithfully each time for a couple years but haven't recently. They have some good vendors there that have a good selection of Rock and Metal CD's. One is Keytunes - was my favorite and really only place to stop at since they always had what I wanted - I would always spend around $100 there each trip! I picked up stuff like Steeler (Germany), Fifth Angel, Alice Cooper, Bonfire, Wrathchild (U.K.), Dionysis, Stratovarious, and many others there. I missed the last recent one but will definitely try to hit up the next one.
If you been to ALLENTOWN, you must have stopped in to VYAGRA RECORDS. I think the guy's name was JOHN. He got me an autograph poster of DIAMOND HEAD when they played a metalfest here in jersey awhile back.
DAMN!
I wish I could get in touch with him!
