trade brokerage fee. As the site initially launched, members used envelopes pre-stamped with traditional postage (a $0.65 postage stamp) and a $0.49 shipping charge was added for each received disc. In addition to the gap between the actual cost of envelopes and postage and the fee charged, this approach represented a significant potential for lost revenue, as members in possession of these envelopes might not use them or could misplace them, with the postage having already been spent. Another drawback to this system was that members often had to add postage if they were including CD cover art along with the CD they were sending. Starting in July 2006 (August 2006 for existing members), Lala.com revised its shipping guidelines and began charging $0.75 per trade for shipping in addition to the $1 fee. The envelopes were charged postage only when mailed, similar in design to Business Reply envelopes.

La La Media filed a lawsuit to cancel Omnilala's "LALA" trademark (see Trademark Trial and Appeal Board Cancellation No. 92048521).

However, users from other countries could still access their songs if they used an American-based web proxy. Lala.com and WOXY.com Nguyen and his website were highlighted in the news in October 2006, when Nguyen announced his investment in Internet-based Cincinnati, Ohio radio station WOXY.com. The investment allowed WOXY.com to go back on the air after a brief suspension of broadcasting. Both sites cross-promote the other; Lala.com promotes the station, and WOXY advertises music that is for sale (or trade) produced by some of the independent artists that WOXY features. In February 2009, LaLa sold Woxy.com to Future Sounds, Inc., an organization that aired programming
