I'm assuming that if you're checking this particular item out on Amazon.com, then you're already a Dream Theater fan, and probably a serious one at that. The Hollow Years Japanese import single is a nice treat for the die-hard Dream Theater fan. I'll try to give you an idea of what you get with this single (which is actually closer in length to an EP):
Tracks 1 and 2 are the radio edit and LP version of Hollow Years, one of the better songs from Falling Into Infinity.
Track 3 is the demo version of the Falling Into Infinity song You Not Me, titled You or Me. This is a nice surprise. I never really warmed up to You Not Me in its official version. There was just something about it, particularly the chorus, that didn't sit well with me. The demo version presented here is a big improvement. The song just seems to flow together much better.
Track 4 is a song called The Way It Used To Be. This is an incredible track. It's probably one of DT's more pop/rock-influenced songs (if you can call a nearly 8 minute song with lots of progressive elements a pop/rock song), and for some reason it reminds me of a U2 song. It's very upbeat and melodic, while remaining a good hard rocker. At any rate, it remains one of my favorite DT tracks, and definitely my favorite on this album.
Track 5 is a live version of Burning My Soul. To be honest, this one really doesn't add much to the disc. It's another of the Falling Into Infinity tracks that just don't seem to work. It is a good live recording though, so if you enjoy the song you probably will want to check this out.
The final track is an excellent live version of Another Hand/the Killing Hand, one of the very first epic Dream Theater songs from When Dream and Day Unite. I've always liked this song, especially when James LaBrie (who joined DT after it was released) sings it. It's heavy, progressive, epic, and a great example of what Dream Theater is all about.
Overall I have to give this disc a pretty high rating. In my opinion, The Way It Used To Be and Another Hand/the Killing Hand are more than worth the price of this import. I'd recommend it to all die-hard Dream Theater fans, though casual fans might not get enough out of this disc to make it worth the high price tag.
