Unfortunately

I’m wondering what turn of phrases one might use to express “unfortunately” in a formal context where an online user is asking someone to add/remove a feature to website:

– Could you remove the music for me?
Unfortunately, no. Many people like it!

In general to express “unfortunately” ou malheureusement, I would use a round-about way to get there; something like the following with “Hakɛto b’à la”:

Ɔn-ɔn. Hakɛto b’à la, nka n tɛ se. À ka di mɔgɔ caman ye!

Are there other options or solutions out there that people use?
