Rock Band no. Guitar Hero 3 yes. GH3 has all three boss battle songs free (Devil Went Down To Georgia being the only one worth while), Halo Theme mix, and some other song I don't remember. GH3's buyable songs are not that interesting. Rock Band has packs and singles. The packs are all 440 pts each while the singles vary from I think it's 140 and 80 pts respectfully. GH2 had the worse cover song vocals in any of the games. Anywho. RB to me has absolutely no replay value at all. Sure you can keep playing songs over and over, earn money and buy all guitars and clothing items but that's all you do and you get nothing out of it except the ability to constantly change your characters looks. GH3 had characters, songs, guitars, guitar finishes, character costumes, and videos. Plus if you're going for achievement points, GH3 has the more interesting ones.
