You have registered a domain name with very good keywords. The search term of "online music" (exact) is entered around 74,000 times per month in Google; however, it is unfortunate that it is the
.tv extension as I'm not a big fan of this particular ccTLD. In saying that however, if you go
www.dnsaleprice.com, you will see that for example the search term of 'CelebrityGossip' in the
.tv extension sold for $1,500 (the search term of "Celebrity Gossip" (exact) has a search penetration of 201,000 according to Google AdWords) - therefore, with this in mind, I would say that it is possible that you might reach $1,000 for this domain name, however, it is more likely to be in the mid-high $xxx range.
