Can bad music ruin a game for you?

Yes. Most blatant example that comes to mind is hacked/bootleg NES games that have had music changed in addition to sprites. Used to collect famiclones. The music in this Lunar Pool hack still haunts me.

I had a few cases in my life when music was not exactly bad but was just boring after first few hours of the game so I had to mute the music in game and lunch a good music on youtube to be able to play longer.

Yes it's rare but it happens, then if it's not possible to mute the music without muting the sound effects, i just mute all.

Personally haven't had a game like that.. If as Zarddin says it gets boring (or is too loud) I just turn it off or lower the volume

yes, good music and good games match together.

Absolutely! Or even not bad music per se, but music that personally I hate (it's all about taste, of course). A good example is The Norwood Suite; it's a very curious surreal game, beautiful in its own unique way; but unfortunately for me, music is very important to the authors here, and it sounds like cacophony to me. I just couldn't play as a result. Another case of a game not really ruined, but fun considerably spoiled is Cyberpunk, there was only a handful of songs I didn't hate there. I must be getting old, I guess.

Couldn't think of any example. I don't count music genres btw

Nope.
To be honest, I rarely notice the music in videogames nowadays. Dunno if it's me getting old or the music getting completely unremarkable, or perhaps it's due to the fact that I usually play games when there's some background noise around (TV, family members chattering etc) but I don't think I've played a game in the last 10 years which music would instantly catch my attention like, say, the Easthaven theme did from the very beginning of Icewind Dale.

I can always disable it if it's bad, So no.

But the opposite happens. Like Gothic III. The game itself terrible but i like it because of the incredible ost.

Ruin partially? Sure, a bad or terrible music is surely a letdown.
But if I can mute the music and listen to something else, it's salvageable. But I'd definitely mention in reviews that the music was bad, even in a positive review.

Not really, if it's bad, I just turn it down.

I'm afraid I will get some blacklists here but I have to be honest, I stopped playing Persona 3 on PSP because I hated the battle theme.
I also had to mute the music for Dragon Quest XI, it's not bad but it's too repetiive, always the same 3 songs.

Omg, yes. I can't deliver an example, but when music and atmosphere don't work out? Just horrible! Or if it's just uzz uzz and woop woop but the game is not like that? Yeah, nope.
Luckily so far I only ever turned the music off, but never the game, bc it was that bad. But I know I had a few games with bad music. Oh, or as AcoWasTaken mentioned: Repetitive, that can be also veeeeery annoying D:

If i can't mute it, YES

Only if the music is integral to the gameplay, like with rhythm games. Otherwise I'll just mute it and play my own music.

I have no idea what you're talking about

Harmony of Dissonance. Bad, tinny soundtrack.

I don't know about ruin, but looking back at my favorite games, its hard to find one that doesn't have at least one good music track or theme to it. I'd say bad music can lower a game's potential and make it less memorable too.

As long as I can turn it down: no.

Good music can save a game or make it even better but I don't think that bad music can ruin a game completly.

I always turn it down, because i like to watch stuff while playing games, i do tend to listen to the first bits of music when i try a new game, but usually i am glad i turn it down.

no, cause i always turn it off(one exception: CP2077-played with music on all the time)

I get more immerse to world without music

Good music can definitely enhance a game.
But I can't think of counter-examples where a bad soundtrack actually ruined a game, since most games with bad soundtracks that I've played were also bad games in the first place.

So... maybe.

I love listening to game music, so when a game has a terrible one, it's rather upsetting. I would have to turn it off and play something else in the background. The occasional times that it's made me turn off a game is when I cannot disable the music but still keep the sound effects, it's either silent or everything on with a toggle, I just couldn't deal with it.

Can a bad singer ruin a good song?
