If your project got you to listen to Dark Side of the Moon for the first time, I would consider the project a success.
All of the Pink Floyd albums got remastered in 2011 and got released as a box set of all albums (the Discovery Box) and as individual albums. If you're going to give Dark Side of the Moon, or any other Pink Floyd, a serious listen I'd suggest the 2011 versions. The 2011 versions are very good, and have very good sound quality. They aren't your typical modern loud and compressed remaster that sounds bad.
I mentioned Dark Side of the Moon because it's one of the more well known albums that has gapless tracks, and where the gapless transitions enhance the overall album. There are other albums that are also gapless. Live albums are often gapless with audience segues between tracks or sometimes songs that go from one to another without any break. Some electronic music, some progressive rock. Classical albums can also have gapless tracks. It's a necessary feature to get right to be able to fully enjoy some music without being distracted by "broken" playback.
