Just went to double check my book on the 3 weeks and I was correct. Quote from book Halachot and History of the Three weeks “Shaare Rahamim Halachot Series”
1.” Music is forbidden because it leads to joy. No distinction is made between live music at a party or music from a radio or tape, even listened to in private. This ban is upheld by Rabbi Ovadiah Yosef, Shilta, and Rabbi Moshe Feinstein, Zt’l.”
2. “Group singing should not be engaged (e.g. in camp) but singing to Hashem, i.e. during Prayer, is permitted.”
3. “One who earns his livelihood in the music field is permitted to work until Rosh Chodesh, Av. However, on the seventeenth of Tammaus and from Rosh Chodesh (including Rosh Chodesh)till Tishah B’Av, he should refrain from doing so.”
