Two soundtracks were released after the show ended: Friends, The One with All the Party Music EP (2004) and Friends: The Ultimate Soundtrack (2005).
This is false, and I have a CSB about it. When I was like 5 or 6 (around '95), my mom worked for First NBC which was in the now Capital One building on St. Charles in downtown NOLA. B97 was in the same building (before it was top 40). My mom took my brother and I there to meet the DJs, and they gave us a bunch of free shite (and an on-air shout out!), including the Friends' soundtrack, and No Doubt's Tragic Kingdom.
ETA: Found the link on Amazon LINK
Original Release Date: September 26, 1995
ETA 2: Read the fact wrong. Didn't see that the were only talking about the 2 released after the show ended. My CSB still stands, though.
