Yes, as long as you ask to within a week of making the deletion request.
The reactivation link expires after 7 days
If you already deleted your account, click the reactivation link in the Account Deletion Confirmation email Musixmatch sent you. That link works for 7 days only. After 7 days, the account can no longer be reactivated, and all of its data is treated as permanently deleted. You can always create a new account, but it starts with no history from the deleted one.
How to reactivate
1. Find the Account Deletion Confirmation email Musixmatch sent when you deleted your account.
2. Click the reactivation link inside it, within 7 days of deletion.
Deletion policy
Musixmatch fully deletes account data whenever a signed-in user requests it. Once you delete your account, all associated data is deleted and, after the 7-day window above, is not recoverable.
