As I type this now, I am listening to the three song preview that Crush 40 have on their Youtube channel. To listen for yourself, visit the video here. The three songs, Sonic Youth, One of Those Days, and Rise Again, are something of a minefield of speculation.
The songs themselves sound great. Crush 40, as usual, have created three perfectly good songs, and I can't wait to hear them fully. The way I listed them above is how much I like them, Sonic Youth first. But talking of Sonic Youth, and thinking of Crush 40's relationship with SEGA, it seems we might be in for a treat. The song mentions other songs that Crush 40 have made, and all of them appear in Sonic games. This could be purely coincidental, but then Rise Again has the familiar feel of the Shadow the Hedgehog songs Crush 40 did.
Back to the songs, they will be performing them at Summer of Sonic live. I would guess an album would soon follow, with these three songs, plus others that haven't been released on any albums yet. One of Those Days sounds to be the cheery one of the group, much like Fuel Me. It also sounds like it will be similar to Fuel Me with the repeating chorus and just two verses, even though three other singers have a song of the same title.
As I said before, Rise Again sounds like it fits in with the Shadow the Hedgehog theme, when compared with Never Turn Back and All Hail Shadow. It might not sound it to begin with, but listen to the chorus of each one. Sounds similar. And of course, Sonic Youth. The most weirdest of the lot, referencing their own songs, and even their own name. "Crushing 40 all the time," sounds a bit weird but it still fits with the backtracking of other songs.
And so, one last time, the songs themselves sound great, from what is in the preview, and I can't wait to hear the full versions.
