Longest continuous playing songs

A Mac laptop with 1,000+ iTunes through Apple Lossless, with Crossfade Playback set at 10-12 seconds. I can play music for 36 days.

Gates of Delirium (Yes... 22 min)
Alice's Resturaunt (Arlo Guthrie.. 18 min)

Thanks everyone, just as a clarification, when I said "the group of songs" I meant where one song leads to another, not where songs are stacked by a player and play with no break in between.

Right now I have been listing to QMS - Happy Trails, I like it!

Thanks everyone, this will keep me listening awhile!

If you like Indian flute music. Check out Hariprasad Chaurasia CD-Rag Bhimpalasi. There are only 2 songs on the disc and it plays for 76 minutes.

Let me get this right because it's still confusing the way you're describing your wants. Are you talking about about albums with no/minimal silence between songs?
