I really like their one (actual) album. If I actually owned it, it would become the album with the single most ... upbeat sound in my entire collection, which is saying something considering I have albums from Heavenly and Helloween.

Seriously, it has a "show them what you're made of, rise up and do your best, you can do it, YEAH!" theme, both musically and lyrically, that is so incredibly potent that they can't even make the obligatory slower ballad piece of the album not sound like something I would have playing to keep me going while running a marathon.

All the miscellaneous songs they've sort of put out one at a time since then (basically whenever there's a new Sonic game, let's not kid ourselves) have been hit or miss, as you've said. There are some I really like and would have welcomed as an inclusion on their album, and some I ... don't.
