Farm - Deluxe Edition Bonus Disc [2009]

Track Listing
01 - Houses (3:40)
02 - Whenever You're Ready (2:57)
03 - Creepies (2:06)
04 - Show (1:02)

Houses is a cover of a 1968 song by Elyse (Elyse Weinberg) that featured Neil Young doing some solo guitar. Check out the original here.
Whenever You're Ready is a cover of a song by the 60's group The Zombies. Listen to their version here.
Creepies is featured in the awesome Alien Workshop video Mind Field (about 3 minutes into it). The intro to the song is a reprise of Little Ethnic Song, which was featured on the 1991 compilation Guitarrorists.
Show is...well, something different.

Anyway, grab the bonus disc here, ripped at 320kbps.

Dinosaur Jr - Goin' Blind (KISS cover)

From the 1994 KISS tribute album. Awesome version.
Check it out here.
*This is only the Dinosaur song, NOT the complete soundtrack

J Mascis + the Fog - Waistin' (single) [2001]

Track Listing:
01 - Waistin' (3:42)
02 - Leaving On a Jet Plane (4:07)
03 - See It As Always (1:50)

Waistin' is from the More Light album, Leaving On a Jet Plane is of course a cover of the John Denver classic, and See It As Always is a short and fast little rocker. The first two tracks are 320kbps, but unfortunately See It As Always is only 192kbps (if anyone has a 320 version, send it on over).
Good luck finding a copy of this, but you can give a listen here.

Dinosaur Jr - Blah, from Melrose Place: The Music [1995]

Yep, Dinosaur did appear on this soundtrack, and it's a song that you can't find on any other release. It's a pretty decent song, a must-have for any completist, worth a listen at 320kbps, and definitely worth picking up the CD for (used on Amazon would be my preference).
Enjoy. *This is only the Dinosaur song, NOT the complete soundtrack

Dinosaur Jr - Feel The Pain (Live Tracks) [1995]

Dinosaur Jr - Feel The Pain (Live Tracks) [1995]

Track Listing
01 - Feel the Pain (5:00)
02 - Get Me (6:03)
03 - Grab it (3:57)
04 - What Else Is New (9:27)
05 - Sludgefeast (7:44)

This is an out of print CD (as far as I know). If you can find a used copy of this, I highly recommend shelling out for it. Of course you can get it here at 320kbps as always, but an mp3 version doesn't do this one justice, so try to find it on CD if you can.
