I'd heard bits of HT, mainly Papercut and ITE, and was into LP a little bit at that point. I got into them more, with SIB, and then LFY, especially after personal events.
My favorite song on HT is APFMH
"Crawl Back In" for me; the song kinda reinforces being an individual. This song came out at perfect time and described how I felt about cliques and popularity, to an extent.
Tracks include:
WFTE
The Catalyst ("Guitarmagedon" Does It Offend You, Yeah? Remix)
You can buy each track separately for $1.29 or the single for $1.99

I couldn't find anything on the boards that mentioned an explicit iTunes release; if I missed it, I apologize for the duplicate post.
