Horn speakers are really bright?

I have klipsch speakers and I think they are quite awful. Terrible for music with the exception of maybe rock and a few other genres. I tried a bit of everything and couldnt get them to sound good.

I now use them exclusively for home theater and I think horn speakers are well suited for that

My comments above are strictly regarding the Heritage series. The only other Klipsch speakers I have owned were KG 4.2s and they were just ok.

Both systems are unnaturally bright. She has way too much breath in her voice and her "s" is way too sharp. This is an audio effect that many people mistake as detail and find attractive at least until it hurts. They also used too much reverb in the mastering. This is not necessarily a result of horns as I have heard them sound quite natural. Your systems are not well set up. Speakers that size should be much further apart and toed out a bit may not be as bright and in your face. It is not your electronics doing this. It is the set-up, the speakers and the rooms. You need to go to a small jazz club or somewhere you can hear an acoustic folk singer. Go to a Richard Thompson solo concert. Don't listen to me. I'm just another idiot with bad hearing.

I want every one to listen to this songs and judge the system

I have found most Klipsch speakers lacking in very high frequency information. But I often find them fatiguing at upper midrange and lower high frequencies. A great deal has to do with pairing them with more forgiving (tube) equipment. I also object to the notion that horns are more sensitive to what they are fed than other speaker types. Granted higher efficiency can often highlight noise, but I think this is a different thing altogether. Best horns I have every heard were intoxicating in a few areas. I have only heard heavily modded Klipsch that sounded decent to me. Havent heard the new models however.
