Nasty Tenant but pays on time

[Marci Stein]

So my tenants, a couple,  moved in
14 months ago and they pay on
the 1 st every month . 

very friendly and nice , until 2 weeks ago when a neighbor texted me they are playing loud music every night . 
I kindly asked my tenant to lower music and the wife said “get over yourself B——ch !“and has stopped responding to me. 
The loud music has stopped, but very uncomfortable to have a renter that ignores me and is hostile because I asked her a simple request. 
Thinking of not renewing next year . Am I being unreasonable, since they pay on time?
