Ya 250 weeks! Pretty crazy...
Ya Nirvana have lots of good songs, but Smells Like Teen Spirit is a great song to go absolutely mental on a dancefloor to and that's exactly what I've done on many an occasion to that song, so it will always be in my top 5 Nirvana tunes, whether Kurt liked it or not 😉
I do hear what your saying though, certain songs get played to death and lose something along the way I guess..
