Rav Simcha Bunim Cohens sefer/book by Artscroll on the “Three Weeks” pretty clearly states that most ( I believe it says “almost all”, but am not 100% certain) poskim agree that recorded music should not be listened to during the three weeks (I didnt read the list of poskim he brings in the footnotes). He even says there are many poskim who dont allow listening to “singing without musical accompanyment” (which I assume means acapella).
It is important to point out that many poskim dont agree with listening to music, live or taped the whole year, zecher lechurban. In one of R’ Moshe Z’l tshuvos about listening to taped music during sefira, he begins by asking, who said it is muttar all year long.
