DSOTM has some killer tunes. The first 5 minutes of the album is great. Great Gig in the Sky and Time are great. Brain Damage and Eclipse are pretty great. But really, if you can't dig the (pretty remarkable) production the album has, I can understand not digging it.
The only Floyd albums I could probably tolerate these days are Animals and Wish You Were Here, but they are both 20 minute space jam albums, again, not a field of music for everyone. I have always found The Wall somewhat overwrought, but there are some good songs in there, and I don't mean Another Brick in the Wall. What makes those particular songs difficult to recommend is that you really have to listen to the album as a cohesive, single piece, and that takes like 80 minutes, not all of them great. The middle of disc 1 is probably the best part, but I can understand not appreciating the tunes without digging the slowish build from the beginning of the album. After that bit, the album get famously dull for like. . .20 minutes or more, until Comfortably Numb comes in, and the whole rest is all good.
But for the most part? Yeah, it's spectacle stoner rock. But not without its angels. You could do a lot worse than Pink Floyd.
And Van Halen was purty good up until 1984 or so. Not a perfect run, but a lot of good rock music in there. Again, you can do a lot worse out of early 80s rock bands.
